Drew: The damascus barrels marked 5/4 are 5 lb. 8 oz.( the gun weights 10 lb. 4oz. near the top of the advertised range) the steel barrels marked 5/2 are 4 lb. 10 oz.(the gun weights 9 lb. 4 oz near the bottom of the advertised range)The advertised range was 8 3/4 to 10 3/4 for 10 ga. Both are 10ga. Could the stamps be a pre-finish and post-finish barrel weight code?
