Can you tell a 6v from a 7.2 volt speed 400 motor from the numbers on the can? How?

Only the numbers are on the can. How can I tell it it is a 7.2 volt or 6 volt motor?

I have 3 speed 400 motors. The 2 6V motors are labeled RS380PH. The 7.2V motor is labeled RS380SH.

If this doesn't help, hook them up to a battery pack, one after the other. The 6V will spin audibly faster.

The S and P stand for the type of magnets used . See the following URL for a full description of 400 can motor specs.

This is so cool and very interesting. I'm learning more and more thanks to you all. I'll re-install the stock RS-380PH (hence the Speed 400 6V) and hang on to the new Graupner when the kit motor goes. I might as well learn (and crash) on the kit motor since it's the same as the Graupner Speed 400 6V.
I used a strip of 1" nylon re-inforced strapping tape (the nylon won't burn off) and the motor was tight in the foam again. I also ran a bead of RTV around the front of the motor to sit over night. Then I'll install the gear box and go from there.
I don't know the total weight of my SS yet since it's still in the building stage.
I'll probably have some more questions on the SS since I'm new to this and I've certainly come to the right place with all you knowlegable people. How can I thank you?
