Sept. 1939 and the frame to BSA London 25th.Nov. 1939the engine case just behind the destributor has the ministry arrow and the inspectors mark-M89. The welbike is a MK. 1 with frame No. 883. I restored this little bike since last Christmas. I would like to thank some of the people who supplied me with parts etc, Axholme Signs for the number stencils, classic transfers for the water slide transfers, and last but not least Villiers services for all the mechanical bits and bobs.
