Thanks for the replies guys.
It could have been a Star branded reel mower.
First thing in the morning I'll go back to Bunnings and take a few close up photos of it and upload them. I couldn't do it today because I was at work.

Pity about the motor on the Masports. The 20" sounds like a good size for domestic use.

Btw, do those segmented little front rollers make the mower easier to turn than a single front roller?

Is a 17" Scott Bonner or 17" Rover 45 a bit small for my lawn area? There seems to be a few of those advertised in gumtree.

cheers.
