Hi,
Nice thread -- a chance to wander down memory lane. And promptly get lost...
Anyway, I can't remember exactly which set was the first one I got, but I'm pretty sure I had the American (Schaper) versions of 3242, 3243, 3244 and 3251. I also had a set of cowboys, but I don't think it was 3241 (I remember thinking I would have liked the Mexican with the sombrero and poncho, but I never had one).
Subsequently I got 3542, 3544 and 3546. And there were some firemen in there was well.
I still have them, and I put up some pictures of them here:
