Now that would be interesting. I've you could find some evidence of that, and find a picture of the bike in that race, that would really increase the value for a collector.
The 'Benotto' too, could be worth some research. It looks like a nice frame, and if you could match it to an interesting brand, it could well increase the value. Good luck!
BTW, what shifters are those?
