Philip, be careful…
There is a good road test of this model in the Third Vintage Road Test Journal published by the VMCC.
The early machines were reputed to be very heavy – 330 pounds; more than your flyer.
For 1931, Scott attended to the weight and remedied a few design weaknesses including the fitting of a 6 stud head, Webb forks and conventional exhaust system.
These later machines weighed under the 224 pound “lightweight” tax concession and had a re-designed main bearing arrangement.
I would suggest you would want the later model.
