Davis Pup Trencher Model 8A5-AO , Need Owners and/or Service manual

[weskm]

I recently acquired a Davis Pup Trencher Model 8A5-AO , And I Need Owners and/or Service manual.

Found a Parts List for it on Ebay, but it doesn't give the details on trencher itself.

I got the Briggs & Stratton engine info manuals for the engine which is a 2001 model.

From research seems the Davis MFG. INC. was bought by CASE then New Holland.

Anyone know of a source I can obtain the manuals from?

After getting the parts manual on ebay it indicates it is a circa 1959 Model.
Uses an Eberhardt-Denver Worm Reduction Gear Box and Clutch assembly
, Any info on that like the oil or servicing is also appreciated.
