Rob, it will be a 1939 civilian machine. Norton swapped the front brake to the right for 1939 (the Internationals had always been on the right, although the ordinary roadsters retained the bolt-on drum).

Does the exhaust downpipe line suggest and OHV model ?

Wouldn't it be wonderful to find the master list of impressed motorcycle census numbers ?

It would be nice to find any more info on impressed machines.

By the way I made a mistake in the block, its C48301 to 58301 Impressed machines.

These Triumph Tiger 100 machines are also probably impressed,they must have been painted in a rush there is paint on the tyres,and drips on the silencer,no rear lights are fitted.
