Looking for info on old Western plow
I'm new to plowing and am just someone who wants to keep the 1000' driveway clean this winter. I recently bought an older plow mounted on a 1969 GMC. The previous owner told me he thought it was a Meyer, but after sending them some pics, someone at Meyer told me it was definitely a Western plow. I'm looking for any information I can find on the pump and the hydraulics (tech data, manual, etc). The pump has a tag on it which reads "MEZ 7002" and some internet searching leads me to believe it was made by Prestolite. I can't find any ID #'s on the blade or hydraulics.
I've attached a few pics, maybe someone can identify it/help out.
