Birdhunter50,
WOW!!!
Thanks for those awesome photos!

What a magic lock system.
Your pictures clearly show the connecting arm between mainspring and tumbler that I mentioned in my earlier post, as well as showing the sear engaging the tumbler very high up and a long way from the tumblers axis or pivot point.

I love the way it is so easily taken apart!

Thanks very much for taking the time to show us how it works.
