Bolek, I tried writing you an email a few weeks back. I was trying to thank you for posting the photos of your wheellock construction. It helped me figure out how to make the sear arm block for the Spanish Miquelet-Patilla-Snaphaunce locks I made. When I grow up and learn how to post photos I would like to show how it was done. Many Thanks. BY THE WAY as a teaser they don't have tumblers so no need for TUMBLER MILLS. Hank Elwood
