I recently purchased an LM470 from an estate sale without the controls. It has the limit switches and winch. I think he had removed them for work, improvements, or who knows what. He was quite a tinkerer, but unfortunately the original was no where to be found. I'm going to build a new control circuit, placed inside a NEMA 4 enclosure.
The circuit for a motor and limit switches is pretty straight forward, 
but I'd like to keep it close to oeiginal.  I can build the whole thing 
for jess than a hundred, or about $400 using industrial switches and 
lights.
Any one have a copy of the schematic? I didn't find one in the manual, 
but could have missed it *(IF)* it is there,
