I've mentioned before that we're trying to extend the Australian motorcycle tome out to 1960. I confess I don't know much about the period 1942 - 1960, and even after searching I've only come up with a handful of names:
Acme, NSW - often discussed here, with much the same Villiers-engined motorcycle built both sides of WW2
Avion, WA - a scooter that made it to limited production
Bryson, Victoria - a scooter that made it to prototype, but probably not to production
Malvern Star, Victoria - mostly autocycles, but some small motorcycles built post WW2, in interesting welded frames
Speed - motor attachment, probably Victoria, maybe WA. Much discussed here, but still very short of info.
http://classicmotorcycleforum.com/index.php?topic=6341.msg31742#msg31742Super Elliott, SA - built their own motorcycles in the 1920s, in the 1950s sold Villiers-engined Super Elliott autocycles and small motorcycles, maybe rebadged Ramblers and Roamers as discussed here many, many years back
Tilbrook, SA - interesting bikes, and I have a fair bit of info
Waratah, NSW - also discussed here a lot; like their prewar stuff their post war motorcycles were mostly rebadged Excelsior-type things.
I also came across a few "specials" built for racing (which I tend to ignore unless they are particularly interesting).
Any other ideas? I fear I may be missing some...
Thanks,
Leon
