From where does the number C16405 come ? Is it stamped on the engine ? It may be a WD Serial ('Census') number from a miscellaneous batch, but as far as I can tell, there was never a Ministry of Supply purchase contract with this number.
It sometimes causes confusion that both motorcycle WD Serials and most early contracts begin with a letter 'C'.
The whole point though about the 'Impressed' or 'Local Purchase' vehicles is that there was no purchase contract number. These machines were bought under a bulk authorisation....they were not confiscated from their owners but generally purchased from manufacturer and dealer stocks, although there were appeals for owners to sell their vehicles to dealers for this purpose.
This is the WD Motorcycles Forum, for all makes, not only for the BSA models...
As you may know, I'm the Registrar for the WD Royal Enfield models. If you send me some pictures of the complete bike, and of the frame number and the various numbers on the engine, I'm sure I will be able to tell you a lot more about this bike.
