Thanks Jack and Mowerfreak!!
You are correct about the Morrison's Jack! Its a bit hard to read in the picture I took so I will type it below.
"In order to obtain best results, first clean the bearings and oil holes. An old toothbrush dipped in kerosene will readily remove old dirt. Apply oil using oil can. After first application, rotate moving parts so that oil will circulate. After second application mower is ready for use."

The tin also states that Morrison's makes Motor oil and Axle grease, I would kill to find those tins!!! I've seen one Axle grease tin, but never a motor oil!
Also Jack, We can't ignore Castlemaine!! Dad has about 5 Castlemaine/XXXX signs in the make shift shed at the moment. When the real shed is built They will all be put on display, if the shed is ever built :p
