Western Gear Corporation was bought by Lucas Aerospace (name changed to Lucas Western) in the late 80's and continued to make hoists in City of Industry, CA until early 90's and then in Park City, Utah.
I have no idea who is doing that work now as the Park City plant was sold to Rolls Royce in the late 90's and is now operated by Triumph for the last year or so. They may still be making the hoists there.
I worked for Lucas Western (Western Gear) in the late 80's in City of Industry and now work for Sikorsky in CT.
