I believe your Olmo track iron to be 58-63. I have a particular problem also dating my Olmo road bike. The lugs are the same chrome lugs as yours, but my headset is a Olmo inscribed headset. My frame (bike) Has a 151bcd crankset and a cheese ball seat post (Jap) that is going to get replaced with a Campagnolo. My serial looks like either M or H and the rest is 488. I am lost and if you have more info, please email me back at xcs_63@yahoo.com. I will respect all info to help me date my Olmo.

I have no better guess than early sixties but I like the bike, maybe a different seat post but thats just me.[/QUOTE]
