you might get lucky if your town is large enough to have a specific bearing shop who can mic your bearing and race and cross reference through their books then check to see if they are available anywhere. I did this with my '37 and outer tapered bearings are available but he couldnt find inner ones.
My original ball bearings were New Departure (ND) which apparently has been out of business for years.

If you are missing one component, you'll need an abundance of the others two.
