Hello Royo1980

No way to accurately date these side-wheels.
The safest bet is to call it a mid-1930s machine.
I have no doubt that the majority of sales would have occurred
between 1936 and about 1940.

Post-war, these machines were decidedly 'old' looking.
Qualcast, by the way, continued to sell the older Model H,
but it was eclipsed by the newer Qualcast designs - the Blue Ribbon
and the Super Seven.

Yes the price difference is significant. The older designs
were heavily discounted though.

p.s. I'm hoping your photos of the Bunyip can be added to the
official History Record for the machine. smile
