sixleggeddog - If you change you're mind on shipping, let me know. I have two Jumping Jack pins that need refurbishing and would be interested in any extra parts. I purchased one recently as "working and playable*" to have a reference to the "functionality unknown" that was given to me a decade ago. I would be happy to reimburse for packaging and shipping in addition to your asking price... but NJ is a bit too far away from northern MI to just "pop over & pick 'em up."
*The recently acquired pin is also not functional - it's in a 'perpetual tilt' mode that I have to diagnose. Pretty sure it's a condition due to relocation.
Thanks!
