The late Tom Dawson said, and he was right,"You can have the finest,fastest lock ever made
and lose the advantages it offers at the vent.His 16 bore Manton rifle had NO noticeable lag when
I shot it. With a sharp flint that lock would produce white hot fire and it sizzled in the pan.
I have NEVER been able to get that result from any lock I ever made.Some better than others but
NOT up to that Manton. The 58 caliber flintlock rifle I cobbled together 11 years ago was fast,
very fast and the lock was what I called a variant Ketland and as far as I know I am the only one that
ever made any quantity of them.I made my own vent from Byrillium,reverse tapered and used one
of Guenter Stifter's cut white agates.One of these locks made by me in the 80's recently sold for$600
