Mark, mine is an O grade 10 gauge with 30" Good Damascus barrels. Weighs 9 lbs. 4 ozs. from 1907.
Just make sure the bores have not been honed out. Chambers should be 2 7/8". Old time way to measure chamber is to take an index card, roll it lengthwise, insert into chamber, let go and let it expand and gently slide it until it stops. Mark with pencil and try again to repeat readings.
