We still have a grey motor powered forklift at work. I forgot to take my camera to work today for some happy snaps.
Solid tyres, LP gas powered grey motor... as you can imagine, not too many keen operators.
Sorry that I led you all astray- on further inspection, the engine is a Gem exchange. Couldn't see the engine number but don't think it would be anything too exciting. Owners don't know when it was swapped over. They've had the forklift since the late 1970s with its current engine.
It is a Yale forklift.
