The mower has a very unique style of base, with those raised fins that run all the way along and then sweep up near the wheels.
G'day
M-FMany thanks for adding your thoughts on this one.
The mystery of this little machine has not been solved.
But, progress has been made ...
As you say, the base is
unique - not in look - but in design.
I do not know of any other maker who joined a round alloy base to
alloy frames for attaching wheels... and then used an alloy blade-holder!
The engine is a JAP Model 80.
I feel my dating is about right.
It is clear this is an AUS made mower.
The fact the base is cast - without a name - is suggestive ...
That's the best I can do at this time.
I hope this one is solved.
