When I first started getting into the idea of building a frame, I used my torch to dis-assemble an old damaged bianchi frame. Kind of a waste of acetylene now that I look back on it, but I did end up with some frame bits that I tucked away. One of these is a seatstay that very closely matches the Bertrand in profile...expect it's about 1/2" too short. The dropout end is finished in much the same way though.
Anyway, in my opinion, it's not a frame that warrants the attention you and sixty fiver talked about above. Then again, if I completely botch the job, I may change my mind!
