It has frame number 8336, which was part of contract C7183. One of 6,000 machines destined for the Middle East from 29/03/1941.
The other marking appears to be Greek, similar to those in this thread: 111 286 with the Hellenic Crown. This is only three digits different from 111 289 shown in the photo of the BSA M20 engine posted by Jan.
Does anyone know what these makings represent? Are they unique identification markings for individual machines, or machine type markings??
Any further information would be much appreciated.
