1955 chevy 6400 first series. The pump and ram on my truck are unlike any I've run across in my search for parts. The pump is integrated into a manifold that has to humps or fluid chanels, the manifold connects directly to the end of the ram. The ram is about 9 or 10 inches in diameter and holds all the fluid, there is no separate hydrolic fluid tank. I talked to a old mechanic at a truck shop and he thinks it was built by a company called Superior hydrolics. I've searched the internet for that company and haven't found anything. Has anybody seen this type of setup before. The pictures aren't the best, my phone is a piece of junk.

I think I've narrowed down the make to either Perfection-Galion or hercules. Not much info on the internet. Perfection is still in operation after a few buyouts over the years so I'm going to contact them and see if I can get any info. Fingers crossed.
