Hi, Folks.
I have NO reference books of any kind so nowhere to look this up. I came across this machine at a recent vintage machinery show here in DowNunda. It hazza fuel tank with the model name, "112F" on it but none of the rest of the machine look to me like any "F" series that I have seen. Any ideas?
Here izza photo of the S/N plate which shows "Made In Australia".

Just my 0.02.
You have a wonderful day. Best wishes. Deas Plant.
