Hello Brian, if I may ask....how long have you been working as a gunsmith? Just curious to know your background and experience for future reference. Would you share it with us please?

Asking that question for future reference is a moot point. Since the last dealings between yourself and I solidified, for me at least, the fact that we will not be doing any sort of business together in the future.

FWIW, this is the end of my Trojan 16's rib. It is 25.9975" away from the breech face after having been very slightly dressed off to flatten a couple of dings on the end faces. (The matting ends 0.131" before the muzzle face)

Should I be worried?

I can't even bring myself to ask.....................

Yes, I need to ask one..............What was the temperature?

Heh! I used my handy backyard CMM, stabilized to current ambient condx (42F and 99% RH).

Allan, I don't think you should be worried at all. But what I find interesting is this. Compare the positions of your front bead sight to the position on the 16 that I posted. They're not in the same position. Why would this be if both guns are/were 28 inch barreled guns as the book says.

[Allan McLane]

Allen, mine's 26" and no, I'm not really worried about a couple of thou ;]

Edit: I took another look at your photo and I think that Brian's right. It doesn't look as if the matting cuts through to the face of the rib the way it would if having been cut and each squiggle (technical term) seems to end just prior to the face.

Allan, 26" or not, do you see the difference in where the front bead sights are positioned along the roll stamp and in relation to the terminal end of the roll stamp? On the 28 inch 16, the sight is much further back along the roll stamp than is the bead sight positioned on the roll stamp of your 26 inch barreled 20. Assuming that the bead sight on the 28 inch 16 is where Parker put it ( there's no indication on the roll stamp that it's been moved back) I'm wondering if bead sight positioning along Trojan Roll Stamps on their Trojan guns was not a highly controlled procedure - anyone have any thoughts?

[Allan McLane]

Scaling off the photos, it looks as if your bead's front edge is 1.4 bead-diameters back from the muzzle face while mine is a bit more than 1.5. This would be consistent with the 1/16" trim you measured, placing it closer to the muzzle now.

Wow!
