Re: Need help to identify #3
May I respectfully suggest you store and display these flintlocks with the frizzen forward. The frizzen is the L-shaped cover for the pan that holds the priming powder. The upright portion is struck by the hammer to produce a spark and simultaneously uncover the powder for ignition.
Having the hammer, the part that holds the flint, leaning against the frizzen just doesn't... seem... well.... ahhhh....right. Neither the hammer nor the frizzen will be at rest. By the way, a guaranteed way of irrevocably messing up your nice pistols would be to allow someone to ''dry fire'' them. The frizzen will end up being scored and the recent scoring will be bright shiny metal - quite unlike the patina on your pistols.
Sorry, don't mean to be meddlesome.
