Are all the 94’s  front sight hood the same or are the pre 64 different than the post 64? Also, is there a trick to putting them on? Any help would be appreciated! Thanks

The sight hoods are NOT all the same.  They have different heights and different slots for mounting. Carbines tend to have a wider slot than rifles.  RDB

Roger,

That is a Great photo representation!  Are any of them marked with an identification code or number?  If they are, can please you post a picture of the marking?

General question for those of you with 1930s (and later) Winchester parts catalogs… did Winchester ever list them by part no. in a catalog?  I have not found a complete list showing all of the various sizes (yet).

Hi Bert, 

Yes, they were listed by part number and were coded by height.  I created a master spreadsheet with all of them awhile back and will post it here when I get back home (flying today).  The sight hoods in Roger’s photo were designed and patented by F.F. Burton for Winchester in 1933.

Also, some of the heights changed over the years and, on top of that, there were some height variances simply based on the spring steel and method of construction.

Jeff,

That would be awesome. Do you know where on the sight hood itself the height code is marked? None of my old Singles Shots seem to be able to give the answer I seek ConfusedWink

Sorry, did not mean to mislead, the hoods are unmarked, the letter height code is part of the Winchester “style” part number.

Hmmmm… one would have assumed that Winchester would have put codes on the hoods to help match them up with the sights.

No codes, it’s a combination of comparing loose hoods to those on unmolested guns and a bit of trial and error. Trying to force the incorrect hood on is a pretty easy way to mar a front sight ramp/groove. Those four hoods on the right in the pic are for M70’s.

rob, I use a 5/16 socket or applicable size to install the side hoods. I take a rubber mallet to gently tap the socket inside the sight hood, which spreads open, and then I install onto the grooves. Works every time and have never caused any damage.

Good idea.

I use snap ring pliers with tape on the jaws (prevents marring the inside of the hood or ramp) to just open up the hood a bit and slide it right into the dovetail.

Bert, et al.

Here is the sight cover (aka “hood”) chart that I prepared with the help of Steve Emmert (Seewin) a few years ago.  I was going to do a WACA magazine article on them but got too busy.  The chart lists the sight covers by part number as applicable to the Winchester rifle model.  The “style” is the height code, “L” = low, “M” = medium and “H” = high.  The information was gleaned from the 1933-1963 Component Parts catalogs.  The dimensions listed are from the original Winchester drawings.  Between Steve and I we physically measured several hundred (if not more) original Winchester sight hoods in-situ and loose and found the actual dimensions to be all over the board (as indicated in Roger’s photo).  Since the overall height of the sight cover changes with the sprung width of the base there is some variance that is inevitable.  That is coupled with the actual height specification which changed for some models over the years so it creates a confusing mess.

I have sorted the sight cover spreadsheet by year and again separately by model to make it easier to determine which actual sight cover was specified.  Again, the chart below only indicates what the catalogs specified, there are certainly significant variances found as measured.  Blanks on the chart are information that neither Steve nor I have so if you have access to those drawings we would love to see them.   

Best Regards, JWA

Jeff,

Thanks for posting that (and please email me a copy).

My take on the wonderful chart that you and Steve put together is that there were actually just (5) different hood sizes, #’s 3276 – 3280.  While it doesn’t make much sense from a logistics standpoint, the referenced catalog part numbers were only specific to the Model they were used on, but they were actually the same dimensionally sized hood for multiple models.

That is absolutely correct.  If I would have led my posting with the bold statement that “there were only 5 catalogued sight covers” I would have immediately gotten pushback since there are a plethora of different heights as measured out there.

Also, if you want to get technical, there are actually 6 but I omitted the sight cover for the Model 75 99A “mailbox” sight since it was proprietary to that sight and not interchangeable with any other sight or ramp.

Before I email the file let me look to see if I have a more recent version, I think I have a later version with more dimensional info, just having a hard time finding it on my hard drive.

Hi Jeff-

Thank you for sharing the results of the work you and Steve did.  Very informative!!!

I’m curious if you located (or empirically determined) any more dimensional data, particularly on the 3277 (BL) and 3279 (BH) sight covers. You’re right, of course, insofar as the absence of dimensions in the couple of parts catalogs I have handy (1939 and 1950).

You made me curious, so I measured a small handful of loose sight covers.  ASSUMING that these are all Winchester parts, which may not be true at all, the BM covers come in just as you say; about 1.050″ long; about 0.450″ wide and about 0.650″ +/- 0.020″ tall depending on how much they’re sprung.  The presumed BL measures about 0.600″ +/- 0.005″ tall, and the presumed BH measures 0.740″ tall (other dimensions the same on both). Not sure the latter one’s a Winchester part though… Confused

I’m aware of the BL versus BM convention in the parts catalogs for the M54/M70, which is exactly as you recorded.  The M70 is supposed to use 3277 (BL) if in 7M/M and 3278 (BM) if chambered for anything else.  I’ve always found that odd in that the 7M/M used the same front sight (0.310″ Lyman 31W or (later) Win 103C) on the same ramp/barrel contour as the other chamberings.  I wonder how closely Winchester actually followed that convention insofar as using a different hood on the 7M/M barrels?  Steve probably knows!!! Laugh

I missed my chance a while back to measure hood height on a bunch of 7M/M M70s, and of the three I’ve got, two have the BM and the third was missing a sight cover when I got it.  But given how often these hoods were removed/lost/replaced, I wonder what was there originally???

Thanks Again!!!

Hi Lou,

Yes, both Steve and I have LOTS of empirical “as-measured” data, however most of it is on the BM cover which is most prevalent on the models I collect and Steve’s model 70’s and 52’s.  I took our measurements, lumped them together into the 3 “style B” groups by the straight side-wall height and then averaged the values to get a ballpark range for the BL and BH.  I tried to use only data from original appearing or NIB rifles.  I did not put that as-measured data on the chart, only the dimensions as listed on the factory drawings are there (neither of us have the BL or BH sight cover drawing).

So, to answer your BL/BH question, our average as-measured dimensions are:

BL – overall height = .568” and overall length = 1.051” – Your BL seems to be a bit higher than my average, although it looks original.

BH – overall height = .686” and overall length = 1.051” – Your BH does not look like a Winchester cover, the end radius profile is not correct.

If we were to assume a nice tidy round design number and sequential increments I would say the actual drawings may have indicated BL-.600″, BM-.650″ and BL-.700″ but those BL and BH heights are purely imaginary and were the anticipated data result.  I was disappointed the empirical measurements did not support them.  

I did not average the inside widths since some sight covers were measured on rifles and some loose which significantly changes that dimension but I suspect it was originally specified to be the same .450” as the BM cover.

I will also note that on some of the rifle models measured there were some cover heights that were not as specified by the catalog, in the case of some NIB rifles that could indicate that Winchester was not always accurate when grabbing a cover to install or the appropriate height cover was temporarily unavailable.

And, finally, I must mention that the above list is only for pre-1964 sight covers.  The post-1963 covers can be dimensionally different and to make it worse, the 9422 sight cover is very close in appearance to the BL cover so they are easily confused.

Hi Jeff-

THANKS!!!  That really helps!!!  Since the (few) parts catalogs I have don’t give dimensions, I’ve been puzzling over the BL and BH ever since Tedk and I were trying to identify the correct hood for his M64 deer rifle…  I could tell him the parts catalog said it was a 3277 (BL), but not what one of those looked like…

I totally agree that the tall sight cover I measured doesn’t look right…  It was something from a parts box and I’ve not been able to identify the maker/age/application.  Sort of looks “Winchester-ish”, but without dimensions I couldn’t say…

All the BEST!!!

Lou
