Thanks Chaps. Tony, if you are able to look up that number at some time in the future I'd be ever so grateful - and also if you could see what was either side of it i.e. if it was a large contract.
I fully understand the difficulties of ploughing through pages of handwritten ledgers. The Norton Owners Club have been endeavouring to compile a database for years using volunteers but it's still not accessible.
I have found a reference to the supply of eight military spec machines with Vokes Air Filter to 'Disney' which I have listed as a pre-war Australian agent for Nortons (in Victoria ? would that be a significant location ?). There does not seem to have been any one Norton agent for Australia as the name Tozer Kemsley & Milburn often appears for other areas.
These may not be the correct bikes as they refer to 38/16H and the one in the picture has the 1937 spec engine (which the WD carried on using).
In answer to Jan's query, I have nothing on Australian use of Enfields but I have got a pencilled note in the back of my old copy of 'British Forces Motorcycles' to the effect that the Canadians were supplied with 250 WD/Cs + 236 further in lieu of Triumphs undelivered due to enemy action. Unfortunately, I can't remember where I read that information so you'll have to treat it as uncorroborated. I know that Triumph did have supply problems after the blitzing of Coventry so it does seem possible that alternatives were sought.
