I have an old style T/C flintlock from which I get 5-maybe 10 shots per flint (good black English flints). I read somewhere, possibly on this forum but I couldn't find it, that substituting a Lyman Great Plains flintlock hammer for the T/C will give better geometry and provide longer lasting flints and better spark. Is this so?I happen to have a Lyman Great Plains flintlock that is not being used. Will this substitution help with flint life and spark? I kn ow there are "new" designed hammers for the T/C, but the ones I have seen on Flea Bay are around $36 dollars, and this does not include the jaw and cock screw, which I am told have to be purchased also as the old style hammer parts don't fit.
