wouldn't you know it. Yes, Reilley1, it was a chrome steel rim with a box profile. This is a picture of one from page 36 of Scagnetti's 1976 book...this is the best scan I could get. I never made the moped connection but, I know several early wheels were sourced from the oil burners

. BTW, the bike this picture was taken from has a really wide mopedish rear 7b style rim so, there may be a connection.
