This is a Trinity vintage motor using slot brushes. Infact the complete hardware on the endbell is different. From my knowledge this is one of the legendary motors made by Big Jim Greenemeyer when he worked at Trinity.

the brush hoods look like the stuff I used on slot car

I have one of these and was wondering what the specs were on it, do you know?

Yes, slot car brushes. Some of the early Checkpoint motors used a similar set-up - I have never seen this on a Trinity motor, I wonder if it was production, or a one-off customization.

That´s easy to explain. The "real" Checkpoint motors were made by Big Jim Greenemeyer who was coming from slotcar racing as some other guys like Erni Provetti in the early days of RC racing. He sold the name later to the guys who are making the newer motors but these have nothing to do with the old real ones.

Big Jim also worked for Trinity several times so you can find also motors like this from Trinity. But all of these motors with slot brushes are very rare and from what I know nobody else was making something like this. The motors with the slot brushes always were the top end of Big Jim motors and very expensive as it was a lot of time involved making these.

I have no specs for this motors. Big Jim passed away some years ago so it will be difficult finding any specs.
