Geez, there are HUGE issues with a model 17-I can't believe these guys didn't let you in on them.
First off, they didn't build enough of them, making them hard to shop for. You only find one or two beat up examples when your gun fund heals up enough to consider one.
The other thing, once people have one or three in their collection, they are loath to give them up. They hang onto those old guns for, like, 50 or 60 years, and you have to wait until they are dead until you get a shot at buying their model 17. What kind of gun do people want to hang onto for so long?
Like I said, these are big problems, so, when your trade gun comes along, you might just want to PM me here, and I'll take the thing off your hands.

Shouldn't be worth much.

Best,
Ted
