Thanks Dave, Walt and others. I had some time this morning and I'm happy to oblige with more photos.
This is an extractor gun; here's a pic of the inside of the forend. It has a typical Deeley type latch, and I can see the end of a wire spring inside (latch spring), not a flat spring as on the A H Fox design. Barrel loop is the typical type with one latch engagement surface.
Barrels have the SB&Co stamping.... Sanderson Bros & Co, with a mill in Syracuse as I understand it. Of course both barrels are choked "4".
Additional pics of the recoil pad. The stock varnish is still over most of the off-white pad base. It would appear the pad was a factory installation when the stock was made/finished. At least, that's my take on it. Frank
