Hi Hawkeye,
This Victa looks like a VC sports model if the base was orange.
https://www.outdoorking-forum.com.au/forum/ubbthreads.php/topics/52244/all/victa-vc-sports.htmlThis mower could be a bitsa ,one way is to get the model number ID is from the air cleaner cover but
sometimes that can be missing or replaced with another.
Looking at the engine number it could be 1976 and the snorkel would indicate it had a G4 carby.
You would think it's an export model Victa with a160 cc full crank 2 stroke motor.
Cheers
Max.
