This machine is listed on the placard as a 1934 T90, but that is most likely a mistake as the T90, along with the T70 and T80, were not introduced until Sept 1936, and were released as 1937 models.

The bike pictured is almost identical to one at Yesterdays described as a Model 5/2, 1935.

This machine is has twinport engine.
