I suppose we have had lawn mowers and sheep shearing machines so a bit of irrelevancy on bikes might be OK.
I found one of those Gumtree junk sellers nearby and he has about 200 bikes. Mostly modern of course but I picked up two correct mudguards, two correct good condition hand grips and the proper Malvern Star rear carry rack. Steve, I will go back to him to get a chain guard once I Google the proper period style.
Just trying to find a set of rubber pedals as the rubber blocks have disappeared. Plenty on Ebay. I originally thought that rubber pedals would be out by 1943 but the Malvern Star forums tell me they went on to synthetic rubber and that is why they all have crumbled away just leaving the rods.
For those so obsessed, they say buy a set of $20 Ebay ones and rebuild the original pedals with the rubbers. The fact that the new ones are absolutely identical to the originals apart from having easily removed reflectors don't suit the concourse blokes (but maybe me).
Here is how I was able to date it.
The 3 stands for 1943, starting at 0 for 1940. The M stands for Melbourne factory. The serial numbers match the Malvern Star forum numbers. The lower frame is BSA as is the back pedal brake and front sprocket (and probably other stuff). Malvern Star like most Australian manufacturers, such as Hartley and Speedwell, were assemblers more than a manufacturer right from 1903. Supply problems during WW2 forced the Australian companies to manufacture nearly everything here and their late war and post war production only used limited overseas stuff such as bearings and brake parts..
