Well spotted Craig. I don't think I have ever seen one, not even as a photo. I reckon an old massey from the same era would have the edge!

I like the design of the slewing on this machine, similar to modern JCB's, I wonder if the slewing as more powerful than JCB's 3 of the same era? also, massey used another system again to power the slew on their machines, would I be right in thinking it was similar design to a hydraulic motor? Interesting features!

This is a picture of the one that we used to own. They were more powerful on the slewing than a JCB 3 and quite a lot of diggers of that time. They were sold in big numbers in western Ulster as there was a dealership in County Tyrone or County Fermanagh. They had a great reputation for working well in wet/boggy ground. They were lighter than the JCB 3 at around 3.9 ton compared to the JCB 3's 5.25 ton and even lighter than the JCB 2's 4.5 ton. Despite the machine's slenderness it could still do heavy work. I still have a 3ft bucket that belonged to it and its a pretty big 3ft bucket at that!

The MF (I think) used a Dowty slew motor. I had one apart years ago when all the studs that held the outer barrel worked loose and Dad had not realised. Basically you have a cylinder in which the king post enters from the bottom. On the inside of the chamber and bolted to the king post there is a large block-like paddle with seals around the perimeter (and against the post) This effectively divides that chamber and when oil is fed to one side and released on the other the paddle moves the king post. Hope that make sense.
