Hi all. I have a beloved Horseman 980 that has been a dependable camera for quite a while. Recently something has been going on with the track assembly. It seems to jam up or go off the teeth. I have a history in camera repair and I've successfully disassembled, cleaned, and reassembled the track assembly several times in the past which has historically remedied the problem until now. Now no matter what I do the track wont work. It just locks up and when it does move it feel very rough. I dread that some parts may be worn out. Anyway, I need to know of a competent source that specializes in or is at least competent with the Horseman 980/ VH/ VHR series of cameras. If anyone can offer a recommendation I would be hugely appreciative. I really don't want to retire this camera. Thank you.
