Mmm not convinced. Ronal were the makers of the ten hole 14" and all the open lug 16" . FPS made the stock 14" Alpina style" in both ridged and unridged spokes and in 6 and 7 ins width, clearly a much larger and longer production run than the small number of "Ronal Alpinas" Indeed all 14" Alpinas I have seen are made by Ronal, even the NOS available now. Clearly due to the rarity the value of the Ronal versions is much higher than the stock 7" FPS. There is therefore a temptation for a trader to inflate the value to the unsuspecting by engraving Alpina and passing them off. Otherwise I can see no reason for adding Alpina next to FPS.
Intresting, the early 14" CSl Alpina (pre Ronal) rims without the extra five small holes had Alpina cast not engraved on the hub.Hi all,
Past the Q around in the Swedish e9 community and the answer that came up was that the real CSL rims didn't have the Alpina text in the cast, it was stamped. They believed that that the cast text appeared with the e28 Alpina and possible but not likely with the e12 Alpina. So the stamped text is from the early seventies. And that goes for the 16" as well.
