A Pair of Taco BumbleBees, lightly used.

These were on our now-patented Delta-T Hydronic Appliance Betas #2 & #3 over the 2014-2015 winter cycle. Taco offered an upgrade with their Viridian 2218's and they were replaced. Been sitting around ever since.
Anyone have a use or suggest a value for these? Can't even find them on Ebay any more.

    A patent holding organization might find a trade school that could use them for training porpoises.
