Hi again,
andyandeva, as you can see this thread has moved to a new home here, as the Photo Gallery is just for photos, not detailed discussion; I hope you understand.
In the description area of the gallery thread you posted:
I stumbled upon two complete non running self propelled mowers. I know they are "ransomes" circa 30's to possibly 40's.
I cannot find very much on these at all. I managed to get both running. In order to save one I was forced to pull apart everything sand and paint even had the seized motor apart. Found many numbers which helped I'd the motor. Villiers mk2.
Any help or info, old poster images etc would be greatly appreciated. This is only my second and third purchase and I'm hooked. I have a feeling this will be a long affair.
I will try to give you some answers to your questions....
(1) Ransomes Sims and Jefferies cylinder mowers were (to my knowledge) imported from England and as such would be fairly rare here in Australia.
Ransomes Sims and Jefferies were the first company to take up the 'Budding Patent and produce the first cylinder mower.
Before the invention of the rotary motor mower (Victa et al) in the early 1950's cylinder motor mowers were the fashion for the middle to upper classes, the hand push cylinder mower was very popular.
Ransomes would have had stiff competition from other imports such as ATCO, Qualcast and locally Scott Bonnar and others.
They were a sturdy little machine and well designed and manufactured.

Unfortunately, I don't know a lot about the Ransomes Minor....but there may be some members here that do and will chime in with a reply.

I will try and answer your further questions later.
