Right after I started producing this lock Gary Brumfield pulled me aside and suggested the cock was too heavy/massive. Of course, he was right, and I promised him I would change it to be more historically correct. I'm sorry I didn't get it done before Gary left us, but it's done now. I also felt the mainspring we were using (the large Siler spring) was a little too heavy for the Late Ketland. I have also made a new mainspring that we'll be using in the Ketland.
