Very nice wheels for your vintage build. Super straight with brand new bearings and wheel nuts. There's some typical signs of age, but no major flaws or flat spots. Just add a standard freewheel and tires and you're good to go!
I can send additional pictures if needed.
Rims: 20" x 1.75"
Axles: 3/8" x 26 tpi
Freewheel: 1.375" x 24 tpi (ISO)
