I just spotted that there are a number of copies of the famous Wheels and Tracks magazines on Ebay.
This is the link to one and then check out the sellers other items for the others.

The numbers available are numbers. 4, 10, 12, 17, 44, 45, 46, 53, 58 and 59.
I have no connection with the seller but thought that someone on MLU might be looking to complete their set of 75.
Regards Rick.
