I know nothing about the mark but I do not believe it is a bargain basement bike. 70's cheap bikes did not come with center pull brakes or Chrome on the frame or forks. Just look at the old Varsity and Continentals that seem to be so cherished. I seem to remember the early Conti's did have center pulls. The fancy lugs are also a clue as to the quality. I say use it and abuse it but do not beat it.
