Have you tried the local hardware stores? Several chains carry them
in those flip down drawers where they have oddball hardware, toggle
switches, springs and such. That size sounds like an old sewing machine
motor. That would be another place to check, if you have an old
fashioned repair shop in your area that repairs, rather than replaces
the motors.

Ace True Value hardware stores in this area stock loads of brushes - a
bit pricey ($4 each!) but beats hunting and shipping handling costs.

If they don't have the exact one - they are easy to file to size and
shape.

You can always sandpaper down a brush that is too large, just be sure
to get all the powder and sand off the brush before placing it in the
motor. I have done this many times for old shavers and other various
small motors that use brushes. The new material may be a little
softer or harder than the original material the brushes were made of,
but that is not a big issue compared to getting the motor running
again.

When I needed one for a fan motor in my car, the only source I could
find was at a vacuum cleaner repair shop.

A long long time ago I had to do the same on a small motor. I took
apart
a D-size carbon zinc battery and the center core was a carbon rod that
I file
down to match the size of the carbon brush. It worked fine.

Try your local hardware store. I know the ACE Hardware near where I live
has an assortment.

That's a clever idea in a pinch, I hadn't thought of it. In most cases it'd
be easier to buy the right or similar brush though rather than file one from
scratch.
