Mike: I think this list is on the 'Damascus Explained' thread, and covers the maker's marks found on Damascus (not steel) barrels used by US makers. This does not include the Remington barrels, and we've yet to find a definitive Belgian mark on a Parker brl. The vast majority of raw tubes had the mark removed in the fit and finish process.

The 'browned' vs. 'black and white' finish has nothing to do with the damascus quality, and I won't go anywhere near who made the best damascus barrels
