Hi Mac-

I’m sorry that I don’t have a bunch of spares anymore.  Gave them away or used them up, I suppose…  

Anyway, maybe I can at least illustrate what (I think) you’re looking for.  The 22G that I associate with pre-war and early post-war M70s is the one on the top (first photo) and left (second photo).  Also shown is the correct “4-step” 3C elevator:

This gets needlessly complicated if you are OCD like me.  Steve (seewin) has several factory blueprints that (I think) shed some light on the post-war evolution of 22-series sights.  I am going to post a couple clippings from these that he shared with me a while ago.  The original 22G had the single scallop in front and a standing leaf that was 0.380″ high.  On the M70, it was mostly used with the “high slide” shown in the photo above and dimensioned in the callout below (this blueprint dates originally to May 1931):

The original (pre-war) 22K had a double scallop in front. It is still pictured that way in some post-war parts catalogs.  BUT…  According to a note added to the 22G blueprint as of 12-31-1948 “this sight base now used in place of 22H and 22K”.  Meaning that, as of 1949, the 22K differed from the 22G ONLY in the shape of the sliding insert, as below):

If you compare the dimensions of the 22G “high” slide and 22K “high” slide, they are basically the same, except that the overall height of the 22G slide (with it’s semi-circular top cut out) was 0.340″ tall while that of the 22K (with it’s shallow ‘V’ top cut out) was 0.315″.  This 1949 version of the 22K is in the middle in both photos above.  These are the sights that I typically associate with low comb M70s made after about 1951-52.  I believe that the REASON for the change in the slide was simply to let the slide be positioned higher in the base without those little “ears” protruding. 

This (I think) was all related to the introduction of MC comb stocks in 1951.  With the MC stock, taller sights were needed to make them useable with the high comb. So the rear sight became a folding Marbles 69 and the Win 103C front sight changed from 0.310″ high (1941-1951) to 0.360″ (1952-1963).  On the regular low comb NRA stocks, changing the shape of the leaf (changing from 22G to 22K), allowed the same 0.360″ 103C front sight to be used regardless of stock style.  At least that’s my “theory” (none of this seems to be written down anywhere I can find).

For completeness, the sight on the bottom/right in the photos is that taller version of the 22K that was used with low comb featherweights that needed an even taller rear sight due to the thin barrel contour.

Anyway, the point of this ramble is that I think the sight you need for a 1947 M70 is the one on the top/left.  They are not too hard to find… 

Best,

Lou

Holy Smoke, what a fantastic amount of time & engineering effort wasted on an 18th C. sighting device that any serious rifleman would have replaced with a receiver sight or scope as quickly as he could!  Just like the original owner of this rifle DID do!
