I have a very early 911 E (# 21) I pulled off wheels today to check part #'s. Interesting one wheel has part # cast for 15 x 5 1/2 part # and 5 1/2J x 15 size but also has in rubber stamp a part # for the deep dish 6 and a 6J x 15 stamp. The date stamp is 6/68 do these must be some of the very first 6 x 15 ever made. I can find the fuchs fox anywhere. The other wheel has had part #'s ground off and rubber stamp marks are barely visible. I think I saw and earlier post from Harvey where he talked about this. Anyone ever seen wheels marked this way.
Merry Christmas,
Phil
