I dont think its a bassani, because I think all of them are hand coned, and welded in sections. It might be a phase 5 pipe, I have seen one before and it looked similar to that. The phase 5 looked pretty similar to a DG though from what I can remember, so its relly hard to tell. Surely someone on here will know what it is for sure.
