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.

Hi Deas,

80J is Equivalent of a USA 89J by my literature---I do not have actual S/No cross-references only prefixes for these later machines.

My Cat of Aust. Product Letter paperwork is dated 11 Feb. 1969.

Cheers,

Eddie B.

Hi, Eddie.

Thank you. This machine has many appearances similar to the early 17K machines - fuel tank behind the cab, batter under the seat, full gear controlled blade, etc., but with a "112F" sticker on each side of the fuel tank and that 80J serial number prefix. I KNEW it wasn't an "F" series 'coz it doesn't have the hydraulic boosted controls like the 14E machines that I have operated in the past or the 112F that I worked alongside in Perth back in 1969.

Just my 0.02.

You have a wonderful day. Best wishes. Deas Plant.

And they are both 112F machines.

Hi Team,

do not know why files are so large as I reduced originals to 40% as per previous times on here. Maybe need to go to 30 % and see what we get for next scans.

Cheers,

Eddie B.
