Glen, I decided a long time ago (3 or 4 years ago) to specialize in Lugers. However, I too pick up what strikes my fancy. In the last year, I picked up a early 32 ACP Savage and a CZ-52.
If something strikes me as interesting, then I am at least interested.
I like them with history, and if they are 80-95% I am happy, more is fine, but I really like one that has a bit of charector, not that a nice, pristine gun doesn't appeal to me. But the history of a piece fascinates me, as I love history and the weapons used in it. WW2 fascinated me the most growing up (that and the Civil War), but the nazi era doesn't thrill me as a collection, although I won't turn my nose down on your collection, or a piece that throws itself at me either!
