Need some ID help please! I have three different Campagnolo push-rod type front derailleurs, that I'm hoping to get model names and dates for. The following is a link to an album containing 5 photos showing different sides of all 3 subjects at once. We should refer to the units as: Left, Middle, and Right, since I took particular care to orient them in the same location for all shots. Please click on each thumbnail, then click on the resulting photos, in order to view them more closely:

Notes about each unit: Left - Loopy "L" in cage logo, chromed cage ahd hardware, removable guide pin (at trail end of cage). Middle: - Open "L" in cage logo, chromed cage and hardware, removable guide pin. Right - Open "L" in cage logo, no chrome on cage nor on most hardware, fixed guide pin.
In addition, the Right unit has (had, actually) a sort of shoulder as part of the body casting the extends out and around the emergence of the push-rod. It has evidently been mostly broken off in this Right example. I initially believed this to be a Valentino model (as a more recent replacement for the broken original), but the Valentinos seem to have the cage fixing screw on the front edge, as opposed to on top like this, and the other two subject derailleurs.
Can some of the 1950s and 60s Campy afficionados please note the approximate years of production / availability and the model name of each subject? I am trying to mate the unit that is most closely appropriate, with my approx. 1955 Torpado with "open-C" Campy Gran Sport gruppo. Thanks for any help!
