Certainly Stovebolt Staff, you can use the info anyway it is helpful.
Now, as to ND19493800's question about his hoist possibly being a post 1980 installation, well how can I say. Here is what I can tell you however. If it has twin cylinders and is of 1949 era, i.e., an original hoist, then it is definately NOT a dumpbody hoist but rather it is aconversion hoist commonly used on grain bodies, etc. Glencoe was a popular product as was Perfection-Cobey and a few lesser known brands. (Johnson, Galion, Marion to name a few) Interestingly none of these companies are in business today. Two of the brand names still exist, Galion and Perfection, but are only shadows of their former selves and the product lines are vastly different from the 40's-80's.
If your hoist has a Williams pump/valve/reservoir assembly in one unit then it was made for a cable control but these weren't available in the 40's, only cast iron gear pumps as I have previously stated. The inexpensive Williams unit was and is common on conversion hoists manufactured after approximately 1970. Cables became popular on PTO's in the 70's. Either of these two, the pump or the PTO could have easily been replaced over the years so it is really impossible to say if your unit was installed after 1980.
