Thanks @J2000E, I do have a built-from-parts 166.0324. It's out for service right now, as my kiddo borrowed it and wore it to the climbing gym. It came back, but wasn't running right. :-/
I also have an original ca. 1967 165.024 which I don't loan out to the climbing enthusiasts of the family. And a modern SM300 Heritage, and a cal. 2500 PO. I love them all, but you can only wear one at a time.
