There is a Lotus sitting in a thriftstore backlot I would like to gather info on . It is 14 speeds with downtube shifters. In script writing on the top tube it appears to say Pro Series. On the seattube it says 3000R . It is a green lugged frame with a tone close to Bianchi celeste with a white headube. The bike is in very good shape. I believe the tubing is Tange. Anybody familar with this model?
