T133 Hydraulic Control Valve

[wildlife]

Can anyone tell me who manufactured the hydraulic control valve used on the T133? It's a 3 spool valve with detents on the center and one side (aux & lift). I suspect it may be a Parker valve, but I can't find any markings.

I had my control valve rebuilt several years ago (2014) by QCC (quality control corp). I was told by my local hydraulic shop that the original valve was built by Duke's Fluid Power, and there was still a tag on the valve. They are long gone, but their assets were acquired by QCC. I contacted the company, talked to an engineer who had me send the valve to them. They sent it back, repainted black, with all new spools and seals . Works great. Cost was a few hundred dollars. I'll have to check my paperwork on the details, but this is what I recall off the top of my head.
