Hi, my hobby is restoring old twin-lens reflex cameras. In one of them (Rolleiflex T) i found this detail torn apart. It is a tape with F-stops values marked on it. I'm about to print new ribbon, but i cant find the font they used. Probably someone here can help me. Rolleiflex T being produced during 60-70's, it had pretty modern look at the time, so i believe that font is appropriate to this period.
