Are you sure you have a Parker Bros. shotgun? Go to the home page and then to the FAQ link and see the first FAQ.

On rib of barrel is engraved parkers brso, maker Merdien Conn, also has twist stamped on it,At start and finish of engraved wording are two are two arrows one at each end, Richard Tucker

Parker Twist 0 grade top lever hammer.

Thank you, that is what I needed to know,Richard Tucker

Richard, Are the barrels stamped Twist, PLain Twist, StubTwist and what number is stamped on the barrel lug?

The barrel has twist on it.The lug has a #1 stamped on it. It also has on the barrel water table a#4 a T with half cresent top and bottom. A small c is also inthis location. I have read on PGCA that there was a little over 5000 guns produced out of twist steel. I also read on another that a 12guage shotgun on a #1 frame with twis steel is kinda of rare. I want to thank you for your help. Richard Tucker
