An almost biblical scene; and how did she get up there in that skirt!? She can't be very stable, standing on the sprung seats of a motorcycle, in high heels, with the main stand of the bike in the mud of an orchard...
The motorcycle is a 1926 Model 16H. The Enfield drum rear brake was first used on the 16H in 1926 but in that year the 16H still used a combined oil- and petrol tank and lacked an automatic oilpump.
(They told her not to touch the apples but off course she wouldn't listen... and we were sent from paradise (that is, flat tank Norton production would cease) and condemned to ride awfull motorcycles with parallel twin engines ever after). Thanks Dave.
