To small set screw is used to set the “zero” position once elevation has been dialed in.  The small set screw then keeps the sight from shifting too low.

Okay thanks , I’m missing one of the two set screws for the locking lever but it seems to be holding with just the one . I was contemplating stealing the screw from the top but not sure it will even fit ?

Hi Chris-

Like BRP says…   The Lyman 48 and 57 series used a similar arrangement, with a set screw in the cross bar that contacts the top of the sight block affixed to the receiver.

The idea was to sight in the rifle for the shortest usual distance, say 100 yards, then run the set screw down until it contacts the base block or receiver.  A dab of something like Loctite would have come in handy to keep it in the right place once set.  That way, you could quickly return the elevation to “zero” setting after raising the rear sight to shoot at longer range. 

Certainly “quicker” amd probably more reproducible than using the scribed index marks on the side of the sight.  Especially for a Lyman 21, which has relatively few/coarse elevation index marks.

Best,

Lou

  

Okay I  see , yeah that makes sense , thank you !

Chris–Winchester Bob sells all the parts for the Lyman 21..Bill

  

Yes I spoke to him already , thank you though .

I’m trying to avoid the $25.00 minimum and $11.00 shipping for the one set screw I’m missing if I can get but without it  …..

Chris,  I would go ahead and get it and maybe a few other odds and ends, such as the pointer, and additional screw, etc.  If you already have them, then you won’t need them!  But if you don’t……just don’t do much with only the one lock screw on the thumb lever as it might strip or let go with the one under use.  Besides, you may go to a gun show, sell the extra parts to cover your shipping or part of the purchase.  Tim

  

Hey Tim , yes I might go ahead and order a few set screws just to have a couple extra , it did come with the pointer but not the font mounting screw for which I just cut down a flat head screw to the correct length and ground down a washer to the correct diameter. I got the sight for a couple hundred which I thought was a good price where they seem to be pretty scarce, so I really shouldn’t be worried about the S&H fee or the few extra dollars I may end up paying to reach the $25 minimum . When I talked to Bob I hadn’t received the sight yet so I didn’t realize it was missing one set screw , thought I was only going to need the front mounting screw and washer . The sight wasn’t listed with the pointer but the seller found it and included it for no extra charge which I was very pleased with .

Thanks , 

Chris
