I picked this rather neglected bike up recently and I'm intending to restore it but sadly all the badge work has been removed. I think it may be late 1970s and has Shimano 600 derailleurs, Weinmann Alpha side pull brakes and Takagi Tourney crankset. The wheels aren't matching. Looks like it had squarish badges on the head, forks and top back of seat tube. Looks similar to Motobecanes of this period but not convinced.
