I think I have the screw you need, Jerry, but tell me what vintage the 48 is in case there is more than one possible candidate. Regards,

Jerry,
Some additional info:
My screws have a major diameter of .060" and minor of .050" which I believe would make them a #0 size. The minor is a bit big and the standard for #0's seems to be a 80 pitch. Your Lyman guy is right on the pitch. I put my thread gauge on a magnet so that the screw stayed in place on the gauge and then using a 10x loupe could finally resolve the pitch issue. It is a 64 tpi.


Also discovered that this head type is fillister and they come in a flat or round style. Here is am image of my sight and these screws. As you can see they are mismatched for head type because I didn't notice the difference when Michael made them available. Both types, however, protrude sufficiently to capture the detent spring when under tension from the knob.


This company has miniature screws and although they don't have the proper one they might know of a source:

Bill and Dennis,

I'm not certain what the vintage on my sight is and I'm not certain how to date it. The screw head on the one screw I have looks like the one on the left in Dennis' picture. The people at Lyman told me what they thought the thread pitch to be but I suppose it could be 56 as they seem to have been going from memory.

If one of you gentlemen would be willing to sell me a screw I would be most appreciative. As uncommon as they are they're likely worth multiples of their weight in gold or platinum.

Jerry-see my edited post.

Thanks Dennis. At least the screw pitch is certain and it is an 0 size screw. Nothing is ever easy on these old timers. Part of their lasting charm.

Jerry LIles

Jerry, Send me a PM with your mailing address and I'll send you a screw. You can repay me by having available whatever small piece I next need and can't find anywhere else. Regards,

Dennis,
Thanks for the magnet trick.
Mike

Bill, will do. Whatever I have you need that I can afford is yours.

Dennis thanks for the magnet trick. I wasn't sure how I was going to try to measure the thread on that minute screw and remain sane.

Darn. I forgot but Bill sold me the Springfield action that Steve Durren used to make my new, beautiful rifle. It is a 30-06 (of course) with a California english walnut stock from a blank sold by the Richter's (Quaking Aspen) with a 24" barrel, Jaeger sidemount and Lyman 48 receiver sight. The 48s staff stores in the butt stock under the trapdoor butt plate. The stock is modeled after a Griffen and Howe sporter from the '30s with a point checkering pattern. The rifle is beautiful. The pictures Steve posted a few months ago are good but really don't do it justice. And slick. It will feed a whole magazine of empty cases without a hiccup. A double heat treated Springfield'03 makes as fine a sporter as any action there is. By the way, if anyone is interested, I believe Steve has another high number action on hand. Oh and you should see the Krag carbine hog rifle he made. I hope he'll post some pictures of the finished rifle.
