Please help to identify the make of my grandfather's rotovator?

Hi,

I wondered if anyone could help me identify this ancient rotovator? I hope the picture loads!! It belongs to my grandfather who is 93. I'm not even sure when rotovators were first invented but it could even have belonged to his father which would make it extremely old!  

Kind regards,
 Tarka

Ah, thank you! I don't really know what I'm doing - it's taken me half an hour to get the picture to load as it was too big or something!   

could be a landmaster, but also could be a versatiller, my norlett versatiller mk5 is similar, but has smaller plastic and rubber wheels, so it may be an earlier model, I think rototiller also made a similar model.
with mine I find you get a deeper dig if you walk backwards pulling it against its rotation.
if it appears to have seized check the gearbox on the shaft first.

hmm tricky, wheels look landmaster but the handles and tank mounting look different.

That;s exactly what I thought.....
