You don't see many of these around... rare?... collectible?... probably not, but interesting.
For one, this version of the Champion "C" (I think there were two) is of a one-piece or "drawn" manufacture. It's not as beautifully-formed as the Mabuchis (*which were actually really nice in this regard... they got at least one thing right ), but it is a cool motor nonetheless.
This example was thoroughly rusted and required a whole bunch of cleaning and straightening/flattening before getting a new coat of paint. Yes, it had the top and bottom tabs, and I cut them off, squaring the open can end afterwards. The completely blown can bushing was removed and replaced with a nice bearing... making for the beginning of a race motor.
For the endbell, I'll use one of these NOS ones I got from eBay that have Champion hardware and what looks like a dead-ringer for the Mura molding, but I believe was also a Champion product.
The magnets are the Champions with the white dots still (barely) visible, and are quite strong indeed! It wasn't just the can that was severely rusted, the magnets were rusted in place... and required some force to get out. I had thought they had been glued-in... but they were simply just "stuck." Interestingly (and most likely because of the thinner can metal on these), the magnets produce a larger "hole," even though they are roughly the same thickness as the Muras and approximately the same long length... maybe a bit shorter. could actually fit a .560" diameter stack in here with a little extra grinding, but instead I'll use a regular .518" stack and just shim the magnets a bit.
So, this one will be "all Champion," except for an arm courtesy of moi. The lighter can and more "closed" can design should make for a great motor.
