Many thanks! I was surprised that the one I've got has exactly the same paint as yours. However, it is smaller size frame. It has 9 speed Campagnolo Chorus. The bike is essentially italian, except for the frame. :-)

By any chance, do you know if decals are still available? And is it possible in theory restore this paint if there are scratches?

Also, regarding the frame manufacturer — it should be quite a large company, since I've read that it is hard to find imperial sized titanium pipes (only metric ones). Therefore only large companies can afford to order a custom pipe set for bike frames. And my Quattro Assi does not have any adapters for the seatpost.
