The second model 17B you have seen would be mine, no? I'm keeping mine, by the way.
Most young guys don't seem to have an interest in old pump guns, the injection molded stock pumps/autos seem to be what they are after.
Good on him.
Barrel number two on my gun started life as a modified, but, is out to .610 at this time. Looking at the hard use it has seen, I wonder if it has worn out to that size, or if it was opened.
Patterning it, rusty and old as it is, makes me think the grouse will be impressed no matter what the dial indicator says.
I should really get it reblued, not crazy about rusty hands.
A model 17 is a useful thing.

Best,
Ted
