Way back in 1972 if I remember correctly, could have been 1973, there was a new cycling magazine that came out- The Two Wheel Trip. I got a subscription for my birthday. First issue arrived, one of the images was reversed in an article, and the bike had a LH drive train. I never got the second issue. There was no third.
The next LH drive side bike I saw was one from Pino Morrioni, he had it at the Nationals at Northbrook Ill. in 1974. Neat idea for a steep banked track. Of which Northbrook is anything but.
