I've now transcribed all the Malvern Star cards recording engine number and the first time it was registered in Victoria and can say the following. Remember, Victorian registrations only.
There were 985 cards most of which were straight Malvern Star machines but some peculiar blow ins as well. The clip on engine era really confused the Registration branch so what they did was record the make of bicycle as the vehicle, so Malvern Star bicycles with clip ons attached are here also. There are two Berini, two Cyclemaster and two Cucciolo plus a couple were they didn't actually say what the make of engine was but recorded an engine number advising it belonged to a 1/4hp, 25cc engine. There was a single 2F powered MS plus another that had its original 1F engine replaced with a 2F. One power crazed enthusiast replaced his 1F with a 125cc 9D engine. Finally, there was a solitary Malvern Star/Mobylette.
There was some wartime production but not a great deal. Malvern Star may have had the engines but we've already read how they had issues making all the other bits and pieces needed to make a complete machine. Anyway, annual war years registrations were as follows. 1941 - 2, 1942 - 2, 1943 - 3, 1944 - 25, 1945 - 4 up until VE Day and I couldn't remember the month of VJ Day. Thats the minimum as there are hints that wartime record keeping wasn't as accurate as it could be. Many reasons for that at the time of course. In view of world events I don't think there was anyone there carefully dotting every i or crossing every t. The odd one got missed out. I'll do a bit more looking around now I have all cards in a countable format.
Last thing, there appears to have been two prototypes. One was the first 1941 registration the other quite a bit later.
Any questions?
