out of curiosity iīd like to take a look at some further pictures, especially the bottom bracket shell and the fork crown.
iīm not sure which brand it is similar headlugs were also found on torpados and stucchis but i wouldnīt say that this is anywhere near. to be honest i am not well informed about bicycles made in the former ussr. kharkov or xb3 is, as far as i know, which isnīt far at all, the same brand.
search the forum, there are some threads about said company.
there is one on ebay right now.
