Hello! And a Merry X-Mas (or whatever nonsecular holiday you may or may not celebrate...)!

It's interesting that the Koga Miyatas posted above are so similar....
I posted on the CR list about this frame and the response I got is that it's most likely a Losa built Guerciotti, Ives, Monti, Ciprandi, Magni, etc....
Apparently Losa was a factory that built frames for companies that were then relabeled. The frames all bare similarities with some minor differences in lug cutouts.

I hope the gentleman who responded to my CR post doesn't mind me posting a linky to his pics.......
This one is an Ives and looks exactly like my frame:

And a Guerciotti that is very similar:
The dropouts have the same file treatment:

Underside of headtube lugs....Same cutouts (the tops are different)


So what I know for sure is it's Italian and likely pre-75 because of the lack of brake cable guides and water bottle braze ons. And it seems likely that it is in fact a Losa built bike for some other company.....Fun stuff!
Thanks everyone!
