Hi,
I have a dumper engine and gearbox/reduction box that I would like to know what dumper its from.
First off I'm assuming its a dumper - looks pretty much like it. It looks to have been repurposed a little - clutch lever added, throttle and its position, a wheel added to the propshaft flange. And a hossing great base!
The engine is a 1968 lister SR1 2,000 rpm 6.5hp.
Gearbox is a 40M PRM
Reduction box! clearly PRM with it being integrated with the gearbox. So 6 forward and 2 reverse gears.

Also I guess does someone want it as it may be available.

Looking at it it could have been used as a winch or bosons wheel, the reduction box I'm not familiar with, but the lister and newage box could have been off any dumper from the 60 70 80 decade?
