G'day Jack
What is becoming clear - through research - is
that Victa were quite happy to search AUS
and worldwide patents for their purposes.
I'm not so sure if Victa searched patents or just looked at other manufacturers equipment as I know
of a few shops in the fifties and sixties that imported USA tools and machinery / equipment .
As we know it was not that uncommon for Australia to look overseas for inspiration ,car manufacturing was
another good example ,the first Holden FX (48-215) Prototype No. 1 was built by hand in 1946 by American and Australian engineers at the General Motors workshop in Detroit.
Yes a lot of the early mower starters used in Australia, were USA designed starters .
Hmm Victa probably saw USA mowers with edgers before designing their edger or possibly had access to patents.
Cheers
