I'm glad I didn't jump in on this when I was originally trying to collect all the lever action mechanisms on mcb. I offered to purchase the prototype, but I never follow through. He told me:
Probably still looking at 6 months to a year for me to get finished, I'm working and going to school so not a lot of time to spend in shop.
and that was dated from the middle of March of 2010. Good luck guys.
