Who knows what of this rare Momo Prototipo diameter 37 cm steering wheel?

[sambapati]

Hello to All, I would like to know your opinion, informations that you're aware of about this 37 cm Momo Prototipo seen in my '72 S. That's absolutely different from the others. It just perfect to me and suits my car (also would any other 69-73 911 the best of all other sport wheels I think). Thanks to its proper size it's not only convenient to handle but I can see speedo freely, too. It's larger than any other genuine old Prototipo seen everywhere, also of repros available now. It has a different Prototipo-script, also different shape of spokes (identical to Momo Regazzoni's but larger, also to Dino 246's but those had no holes...) lower spoke is partly wrapped in leather, too, not like "the usually known prototipos". I bought it on a swap meet in Germany, it had a BMW boss and button that I asked to be removed, supposedly taken out of a BMW Alpina CSi, therefore but has no "Alpina" script that all such BWWs' had instead of "prototipo". I saw no one other like that yet, came across by chance on a rainy, muddy day and am happy to have it in my car. Awaiting your feedbacks on that "mistery" wheel. Thanks.
