I have acquired an LC Smith, 12 ga. Field Grade, serial number R86266. I measured the barrels at 31 in. so I don't know if they're 30 or 32. It's in fair shape with the stock being the roughest. I am new to the Elsie shotguns but love SBS's. Could anyone tell me anything about this one, like year it was manufactured and what it is probably actually worth? Appreciate it.
