I many years ago found a motor that was a prize find for a teenager. The shaft was the same size as a Meccano axle. The only other was the non reversible BSR record deck motor.
This little DC motor proved to be even better when I took it apart and checked it out as there were two sets of fixings for the brushes and the 15 degrees also comes to mind. By fitting it in the alternate positions gave half speed and double torque but always the same power.
You now have a vintage variable speed power tool there in your workshop.
It is a nice low mileage motor going by the low wear on the commutator. Perhaps those modern sealed bearings will keep the swarf out.
Looking at the quality of the castings and just how little of the old paint is still there I would consider waxing the natural iron so that the quality will remain on display when the restoration is complete.
I can't in any of the photos see what colour the old paint was anyway.
