I checked their website, and they no longer have it listed.

Dang, I wonder if anyone else still has these?

I'm down to one good one, but wouldn't mind having an extra.

Another engine that might make sense to try and find is a Nelson .15. I know some of the older pylon guys must still have some of these around that they would sell at a decent price. There is not much use for them without a QM15 class anymore. These engines blew the doors off the Conquest.
