Hi, i found an Hamilton frame too, for 24" wheels like yours, about a year ago.
I'm also trying to gather some informations on these frames but they're really rare.
I live in France, and found it here with no info at all on the frame history or the brand, and without wheels or gear.
Mine has a Bio-technica/Mecacycle (famous french builder) stickers on it, maybe from a sponsorship?
Here are some pics:
Here are some details, it has Excell tubing, chromed lugs, and a oversize diag tube:
So i'm desperately trying to find sattui composite wheels now, or any 24" carbon/composite (disc?) wheelset, but none showed in a year. If someone got a plan for them...
Also Thogsez, if you could repost you article in higher quality, i'm really interested, thank you.
