Long story short, I was working on my Mk III Mamba and took the stick out, but it was late and I stopped without reassembling the unit. I believe I set the lock down on a box and it fell in and I didn't notice. Wife used the box to take stuff to a local Goodwill donation and there you go. Not her fault...totally mine... stupid of me.
I am willing to pay for a new one if available from VKB. If none are I guess I will have to wait. I suppose I can put my old Mk I gimble back in the Mamba with the old old style PS3 connector for now....I'll miss the cams action, but the old gimble is still a very good one.
