I would think that rear wheels from a 26-27 Model T Ford would be very close.
If you've got the Star hubs, you have the main thing you need. Maybe you could take the Model T wheel apart and assemble it to the Star hub, making changes at the inner end of the spokes if needed.

Spokes for the Ford T 21" wheels are the same for Star with 1/2" tenons. Bimel fellowes use 5/8" tenons. Should be an easy swap.
