BB threading reads 36x24T.
I guess that seat post diameter is 26.8, but it seems that the lug got a bit elliptical so my old seatpost won't fit right in.

BB width is 70mm.
There's no braze-ons, only a clamp.



Interesting thing. When i checked the downtube under some light, some letters faintly came into view.
sorini or soridi or something similar. "sori" definitely, the final two letters i'm not sure of.

I appreciate your help and interest
