Wow indeed!
Thank you for the history MauriceMoss , very informative with all the different tie-ins. I bought that frame in Vienna from a shop (other bikes purchased private sales in Italy). If that frame was on sale 2 years ago I can see why the shop gave me a very good price (60 euros; plus I purchased a bunch of NOT CHEAP parts from them as a package deal) when I bought it a couple months ago. I got a French threaded Zeus BB cups (new, but need spindle; can I use any brand?), and Zeus: supercronos RD, FD, chainrings (drilled) & seat post so I guess my mind was already heading towards the Spanish side of things. I will try to build it with Spanish parts if I can. I think the Olympic or Olympia pedals are a Spanish make, got them in Italy though so maybe not. I guess I can leave the decals in place without having a definite ID now that there could be more than one possibility as to the actual builder.
I hope the Chiementin(?) frame's history is not so convoluted. Thanks again juvela for the insight regarding that frame. I am pretty sure it is not a Galmozzi, certainly not one like the example in the link. That frame looks like someone went to the hardware store and just purchased a bunch of individual letters to stick on it; a much older frame than the "Cosme"; 60s-early 70s(?). I don't know anything about it except that it has a 70mm BB w/Italian threading. It was a dirt cheap yard sale buy (about 40 euros) so nothing lost; perfect for some cheap Italian parts if it turns out to be a run of the mill frame set. I will post it separately as suggested.
