Gilles:

To address your questions first:

(1) No.

(2) Yes.

The difference is in the number of vent holes in the rim. Early series had 12 holes, late II to IV (I believe) had 8, more elongated, holes. If your friend is interested in being CORRECT, check the date code on the rim. I have several early series rims available, 60 and 62 codes.
And they need to leave the garage this summer…
