What brand or type of cylinder?

[POC]

I have a 15 year old Mahinda sub-frame backhoe, model 3710 on a 3215 4x4. One of the outriggers and the dipper are leaking horribly. I'm looking to rebuild, but the kits all want to know what mfg my cylinders are. I have no idea. Any help?
Thanks

Some manufacturers actually stamp part numbers onto the barrel somewhere but not many. As a general rule I don't deal with seal "kits" for hydraulic cylinders unless there are no other choices, or the "kit" is something I know will fit and the price makes sense. I take the cylinders apart, remove the needed parts, and take them to have them matched by dimensions. I have a much better success rate that way.
