I was digging for goodies at an antique place....you never know what you're going to run across. I found a Lyman #55 powder thrower and saw a little powder horn with the price obscured. After paying for the Lyman #55 I asked about seeing the horn and the purveyor said he had a box in the back with more muzzleloader stuff. Sure nuff a box with 3 tins of caps, a antler flask with 1/3 lb of real black, ted cash capper, leather ball flask, decent measure, couple of flints, ball starters wrenches and jags. Also in the box a New Orleans Ace. Apparently the box had also sported a flintlock pistol; someone beat me to it. One tool I have no clue what it's for, I suspect it's for maintenance of flints...any ideas about the flat tool?
