Yeah it's sort of close but I'm not convinced: for one most Olmos from that era have at least something pantographed, the reason the example shown doesn't is because it's a "budget model" with Falck tubing and nearly no chrome, GPM DOs, too. Bet yours has a 27.2 seat post and rifling in the steerer, bet the Olmo shown does not. Add to this all the other details (forkcrown and even the TT guides which are similar but no match). I'd say Olmo is one contender, but I wouldn't close the case...yet...
I'd still like to see those additional pics.
