Are they still in business,if so, where ? We have searched , to no avail. We are looking for a work manual on a 50 ft. ( single control handle ). We think it's a 1979-80 model. Two separate buckets, either side of boom. Upper fiberglass & lower metal boom. Center mount ( not continuous rotation ). Low milage on F-700, no former tree work ( used for lighting ). Would like to buy manual for reference. Unit has no cables except for bucket articulation. Good solid unit that was shed kept & has all work records but no repair manual. Any information would be appreciated.
