Weird Pump - kinda neat though

[Stepmac]

I bought this strange Browning because I trust Browning designs and it looks like a turn of the 19th Century gun and with a little work it'll clean up to be very nice. The machining is spectacular which is what drives many of us wild about 19th Century guns.

I removed the barrel and cleaned the tube and she is nice and shinny inside. Very little rust. It still has some white buffing paste here and there. Someone obviously wanted to gussy the gun up and then pawned it instead.

I also found a very faint WW (Winchester Western?) PAT mark inside in between the barrel lugs.
