I personally would scrap them and any other metal I could find around the house/work. You won't get the top copper price but a lower mixed price maybe around $3 a kilo. Its amazing what they will pay for. On the way to the scrap yard I would stop at a motor re-winders to see if it is economical or possible to rewind them.

I would at least look for someone who would be interested in re winding them.

Also, I hope the 240V Ballast mod is fused.
