Great article and pics. Interesting nose cap that I have not noticed before. Appears to fully wrap the forestock and be open ended. Is this a bit of a rarity, or have I just not noticed it before now?
My (very limited) understanding is that this was common to that area, but not elsewhere. But I think the main reason it seems so rare is just that we so rarely get to see the end of the muzzle. Collectors are usually the ones to pay for photos, and they don't always provide photos that are important to builders. (It took me a long time, years ago, to finally discover that
any rifles had an open-face muzzle cap, much less one wrapped around like this one.)
My (still limited) understanding on the joint is that it was a lap joint, which in this case must have been very carefully tapered on both sides so as to overlap without adding thickness. I've seen a photo of one that was more casually done, and the joint was visible, and positioned in the bottom of the barrel channel.
It would be nice to hear from some on here who have made caps like this!
