I looked at my old sights in the glass, if I had it, it was free to your door. Fifty dollars for a set screw is something I will not ever understand fully.

Rick, Understand it or not.. a rare part is a rare part. In the discussion above I have heard some rediculous thoughts..jam it in there, go to the hardware store etc. If you are talking about a $3500 Artillery a 50 dollar part to complete it and bring it back to a treasured collectable is a stone bargain. Now it looks like some who have contributed here want to Bubba up their guns and gentlemen.... you are certainly welcome to go to the time, trouble and expense to do just that.
I could care less if I ever sell the one and only rear sight Artillery screw I have ever come accross. Truth be told ...I am just as well off to keep it as I may need it myself someday. I have found many parts to be extremely expensive and many to be unavailable at any price.
Now if you have a cheap shooter it might pay to just spot weld it in place...
And to be clear... the screw I have is the adjustment screw for windage with the spanner top. The set attachment screw is probably more common. It is the same for the front adjustable sight only longer.
