[QUOTE=Branimir;14538595]Hm, since bike has been repainted, there are no letterings on the bottom bracket. Also does this part of top tub look like Zullo?

Hmm, it might just be a Zullo fork on another brand's frame.
Here's another shot of the cluster on my Sprint for comparison.
I don't think the frame looks like a Zullo.
Could you take a straight on shot of the front of the head tube?
Why don't you email Zullo directly with some pics for id purposes?
They have helped me with a few ids.
