I was trying to sell these for reuse, but now pricing as scrap. Solid brass, with chrome plated brass bases. No steel.

Cool set of Solid brass double acme thread skylight winders for repurposing or re milling for other uses. Would make awesome accents on custom articulated furniture, use them as legs or supports. They measure 15 inches long when fully extended. Solid brass, with chrome plated solid brass fixing lugs. All thread operate smoothly.
