Very nice score Dave! That wood is beautiful, that is going to be one pretty gun after you've given it some "gunsmith love". I have that LeFever 16g that I'm going to have some V springs made for, if I can't find originals.
I know I'll get flamed. but hanging those Damascus guns on a wall is a sin. I know you are a gunsmith, but I have had many conversations with doublegun collectors and there is nothing wrong with shooting a Damascus gun with modern reloads provided the gun has been thoroughly inspected by a gunsmith.
Damascus barrels were popular up through and after WW1. Unfortunately, being a 3 man process coupled with the fact that most masters at barrelmaking were killed in the Great War, it fell out of favor and became extremely expensive to continue. Most higher grade guns were still offered in Damascus as an upcharge until finally being phased out due to labor costs. Leaps in modern manufacturing due to the war also sped up the transition.
In an earlier issue of Double Gun Journal, Sherman Bell published a series of articles titled "Finding Out For Myself" in which he tested modern loads on some older Damascus guns, even going as high as 2 1/2 times normal loads before any stress was seen in barrel integrity.
