John Spinks wrote the following description based on the photos provided.

The rim is off either a 1934 or '35 Airflow that has been modified to fit up to a '36 Airflow with the extra holes for the dowl spigot that was used on the '36 models.
The rim also does not appear to have the safety bead that was rolled into the '36 rims. This safety bead was not on the '34 & '35 rims.

The rim and tire is in Dayton and I will be at Hershey in October and can meet you there. The price is $100.00 and you can reach Rick weekdays at (937) 271-9502 between 9:00AM and 7:00PM.
