The serial number has an extra digit, but the gun looks pretty nice for $70. By the way, Granddad's pigeon gun, an E Grade #10,130 is a pivot lever cocking rod gun with a bunch of extra solder from a less than careful repair around the extension rib area and about three inches forward. I've only had the gun since about 1957, so I'm not sure if the repair is going to hold up. I've never heated the area to find out, only assume it is solder overflow.
