Can you help to identify these frames, bikes or parts?

Bit of an update to those riveted to my search to find who built my frame, I know there must be at least none of you. I swapped the fork over for one I can run a brake with for the time being and the original has Campagnolo ends... Well if it is indeed the original. Also I found traces of red paint in the head tube - so i can safely assume some of the bike was painted red at one stage... Perhaps. Maybe more clues will emerge when I strip the paint off in the summer.

Hurrah for bike detective work, why buy a boring branded bike when you can waste hours trawling the internet in search of the truth. I think I know every single bike on velospace and fixedgeargallery now.

Can anyone help me out?

This is my "Tossini" that I bought last year.

Now I really should have done some homework before I bought this guy, with a name like Tossini it must be an Italian frame right, and look - there's an SLX sticker.

However it wasn't until I gave it a bit of a service that I realised he wasn't who he's pretending to be. First off - the tubing is pretty nice, light with a good "ping" and takes a 27.2 seatpost - but it ain't SLX as there's no rifling down the seat-tube. It also takes a british threaded BB, so the chances of it being Italian are greaty diminished!

That said - it's still a lovely bike and I'm planning on respraying it soon as the paint is really showing it's age. It's probably been resprayed at least once in it's life as there's evidence of sandblast in the seat-tube.

My theory is that it's probably a 60's/70's Dutch/Belgian frame that someone bought in the 80's and "Italianisised" it as was the fashion. If anyone could throw any light over it I would greatly appreciate it... the lug's in particular are pretty unique:(although badly painted!)

Thanks very much!
