You don't see many of these around, that's why I grabbed it.
Yep, a pre-82 Model 64. Not that common. I think I have a two inch, round butt, one of those. I seem to remember owning it. Might have sold it, but think it's still in the safe somewhere.
Pre-82? Yes, but it's the no dash 64, the only 64 with a pencil barrel. Made for 2 years.
