There is a guy where I live who is like that, but only with 70s-80s 10 and 12 speed bikes. He rides on tubulars daily. He does daily all of his bikes and has a bucket of about 50 corncob freewheels as he wants more range when riding. He also makes custom replica logo stickers when restoring bikes.There's a guy here in Poland... I bet he has one... or two, or at least knows what brand it is
The guy is a total guru when it comes to old bikes, and has tons of them (also tons of money, since he recently bought an 80's Bianchi Vento as a "daily bike").
It works in most cases like this - post a picture with the frase "please help identify". He shows up, sells you the complete history of the bike - brand, model, production years, and adds "I have two of those"
It's the first guy I've met that stores his bikes in parts, cause he lacks space to keep them in one piece...
