Dear All
I want to identify Douglas bike. It is propably bike T6 witch cap. 600 cc from 1931
engine no EQ803
Frame no YF1765
Can you confirm it?   I will be grateful for answer.

Best regards Artur


Hi Artur,
             According to the Douglas machine register it is listed as 1931 S6/D31 600cc.



There is not a lot of difference between a S6 and a T6, or as they would be known in 1931, the D31 and E31. Both used an EQ prefix engine and a YF prefix frame. There were some minor trim differences, but the biggest difference was the front forks. To verify if it is cataloged correctly in the LDMCC Register, the D31 (S6) has a central compression coil spring. The E31 (T6) has two extension coil springs at the sides.



Dear Gents 
Thank you very much for answers. This is what I need.  :)

Best regards Artur
