So I guess my father bike falls into this contract, I guess from the little I know I expect the picture was taken in Italy.

We were suppling vehicles to Russia, when did this stop? Could some of the contract have been sent there?

Two ways. Some bikes came into Poland with polish soldiers returned from west to Poland. But I think not so many. That peoples were 'enemies' for new occupants and the most of them died in prisons after they returned to country, so next who wanted to return didn't do that.
Next way is lend lease. Incedible quantity of equipment and vehicles came into Murmansk city. There were some BSA and Enfield bikes.

On my bike are matching numbers on crankcases. 3867. And there is letter B on left crankcase. Any plates and extra numbers. I have matching numbers on frame and engine.

A total of 1706 motorcycles were sent to Russia as lend lease in April/May 1944,most were BSA M20s (around about 900?)the rest were Velocette and Matchless models,photo below is of one of the Russia M20s taken in Moscow,has yours still got the knee rubbers the same as this photo.

The most known lend lease bike in Poland is WLA. 1700 bikes from England? Or all? I think we have now few hundreds lend lease Harleys in Poland. I havn't original knee rubbers. I remember one, but it was lost when I was young. It was smaller and thicker than standard rubber. I don't remember BSA logo on it.
