I really dislike Black bikes when trying to ID the details. I just started wondering what other bikes this could have been originally. My thoughts were the only thing this could be if it's a 1962 or later with the just a single top tube would be a Speedster light weight, but the downtube on those are straight. Looks like the chain stays have been reworked wider, then another good look at the seat tube joints that I noticed had been messed with also. Appears the back half of the bike was all redone at the seat post and this could actually be a modified Cantilever frame looking at the top seat post area where the top tube has been messed with. The twin bars were dropped lower than an original to probably take care of the mess from cutting off the cantilever bars. Pretty extensive modification if it was. Cool frame for a modified Cantilever though.
