My 1940 Champion uses the same condenser.
The rating on it is .16 to .20 mfd.
Any condenser that will hook up and that’s in the above mentioned range will work.
The chart below shows various condenser makes with ratings.
Only problem is most of these you find will be old stock, and reliability will
be in question.
When in doubt, I usually retrofit or replace the condensers with a new electronic’s
capacitor. Lots of information on site if you search.
The points can be taken apart and dressed with fine sandpaper, working
from 320 grit up to 1000 to remove pitting and polish them up nice.
I usually clean them afterwards with electrical cleaner.
