Massey 175 hydraulic parts guru needed

[EdinOR]

So on my newly acquired 175, serial#9A 64010, which looks to be a '69, the rockshaft wouldn't work so I figured I dig into it. I got the cover off and the problem was obvious....rings missing on the piston. Now I'm trying to find parts and keep running into dead ends. It looks like what I understand a "grey market" tractor would look like. None of the stamped part numbers match up with my tractor parts book show. The piston is a special (modified???) creature as well. Here's what I have;

Case cover



Cylinder


Connecting rod


Piston



I'd appreciate it if someone could help me solve this puzzle and give me some advise on which direction to go on my rebuild. I suppose if I knew what the cover came off of I could just get parts for it. Or are most of these parts interchangeable? Thank you!

Get a hit on the p.nr on the piston, can be a Ursus number, Ursus did and does license MF designs.

But I'm quite shore a MF part do fit. Picture of the rear end would be interesting, if it's a 69 you should have dry brakes.
