Hi Chasekell, and a warm welcome to the forum.

It's great to have another Scott Bonnar owner on board.
We all like to learn new things and tinker here.
Your machine is a Scott Bonnar "Bonmow" Model 19, 14" Electric. These machines were first manufactured in Adelaide
in 1953, and yours is the 790? (the last digit is hard to see in the pic) in the series. The 14" machines were also known as "terrace" mowers and usually used on smaller sized lawns.
Great pics and

on a good score.
Once again, Terry,
