"Welcome to Marble Connection"
Looks like a Vacor serpent IMO. Peltier Supermen have a different structure. Hang in there, collect what you like and again.

Here's a couple Peltier Supermen showing the classic ribbon pattern& color "flip flop" though they were made w/ a type of Yin Yang pattern, swirling effect & in, different sizes as both of these are. Time in the hobby will make it easier for you to differentiate them from other manufacturers. Whatever you do have fun doing it.
