The following numbers are stamped on the underside of the barrels and the frame flat: 653xx that I assume is the serial number.
The number 1173 is stamped on the barrels, frame and inside surface of the trigger guard. Could that be the date the gun was made?
There is XXV stamped on the barrel flat. There is also 15.9 stamped on the underside of each barrel. Also XX on the left barrel and XXXX on the right barrel.
I measure the chokes as .010 for the right barrel (Lt. Mod) and .030" (Full) for the left barrel with my Skeets Bore Gauge.
Although I don't see it marked anywhere, it appears that the gun is chambered for 3" shells. By using a stiff piece of plastic as a gauge, the chambers are about 0.1' longer to the forcing cone than my 20 ga Ithaca SKB that is chambered for 3" shells.
