I just checked. My dealer has a 4" Model 19 listed...doesn't say which dash, but I'd guess a -4. It's a P&R anyway. I'm a sucker for a 4" Model 19, so I'd probably get that one.
There is a 2.5" 686-3 locally with box etc that the guy is asking $1K for. I think it is a decent buy but have no interest in it.
But if someone were to just hand me $1K with the OP's conditions that 686 would be in my safe right now
5946.
I found it and will pull the trigger on it tomorrow.
I'd get a pre-war K-22 Outdoorsman. (Sold mine a while back, downsizing, and I miss it.)
