Please pardon it took so long to get posted I mistakenly double posted this topic. I did wait 3 or 5 hours before reposting. I'm on my phone. Sorry.

I have plastic micrometer. The seat tube reading was 26- 27ish mm & The bottom bracket is 68 ish.
I'm at the Fire Dept till Sunday morning so it will be a while till I can break the bike down. To look for threading #s , rifling or any identifiers in the bb or headtube.

I keep coming across Olmo BBs with simular cut outs. But it doesn't seem to fit in my mind that campy dropouts would be on an olmo. Aren't they the Italian versions of schwinns.

If a moderator wants to delete this or lump it all together I'm fine with that.
