They are manufactured by GBM, we sell those two motors to a customer in very high numbers, you most likely got them from one of their machines.
We have full datasheets for them if you want them.
PM me and i can get it to you next week when i am back in the office.

They are quiet small so I guess not useful.
Looks like they came from Jameco but I can't find specs anywhere.
They are 4 wire so obv. bipoller. How can I find out if they are any use.
Can I just start with 0.5a and see when they get to hot or what?
