Have recently found and purchased a Bycool Evaporative Cooler from a bait shop at Heron Lake, NM. I tried to find some info on this unit. All I can find thus far is that it was made in Colorado from the mid seventies to mid eighties. Would love to talk to someone who owns/owned one. Everything on this one seems to work and is in good shape. There is a reversible fan, and can use just the fan or have the cooler on with the fan. I've not hooked up water yet, but will in the next few days to see if that end works or not (float/shut-off). If anyone has a manual or documentation for this, I'd love to see a copy. Thanks to all in advance for any responses.
Here is a link with a brief history of the cooler....

I have the model that is shown mounted on top of the tractor cab.
