Now the bad news:

The bolt, follower and 150 slide Lyman were all plated. Seller stated he didn't have the sight, but a followup email turned out he did and he let it go cheap. The nut is broken off the bottom of the elevation stem. I have replaced the follower with a used blued one and the bolt with a blued one from a serial number appropriate steel code lot. I picked up a 150 slide Lyman on eBay that will go on to replace the plated one.

It ain't ignorance that does the most damage, it's knowing so derned much that ain't so! J. Billings
