First, thanks for everyones input and sorry took so long it get back to you all.
I can not see any makers marks on the Damascus barrels, There may be a T but it could also just be a couple light chisel strikes.
I took the fore end metal back out of the wood to photograph the numbers, noticed besides the serial number it also has the grade 2 number so if it is a replacement I would assume it was done by Hunter Arms.
To be honest I bought the gun with the idea of just flipping it. I took it out today and shot a round of trap just to make sure of function. May have been a mistake, crushed 23 of 25 with low pressure 7/8 oz loads, this seems to be one of the most naturally pointing SxS's I own.
Are these early Smiths overbored? Cleaning patch is a loose fit compared to my other 12 gauges and a dime is loose at the muzzles but it breaks birds like full and full.
If I keep it I am going to have to get some work done on it, the left firing pin and bushing have been poorly replaced and will hang up or pierce the primer and the roller extractor seems to have a missing or broken spring, other than those 2 items the gun shoots great with nice trigger pulls.
If I decide to keep it any idea who to have do the work, my go to gunsmith would prefer to not work on LC's anymore.
Thanks again.
