Tow worm and tow, spare flint, hand made vent pick, hand made turn screw, 2 balls wrapped in some patch material and an antique oiler tin with a needle applicator for lubricant.....I know it might not be PC/HC, but I was thinking about making up a small wood vial with a screw top (maybe lacquer finish)and put a little powder in there as well??????with that addition, ifn I ever lose my shooting bag and manage to hang onto my gun, I would then have enough stuff to clean her, make small repairs and load her twice more....any of you more knowledgeable PC/HC people have thoughts on a more traditional very small (150 gr) powder carrier that would also keep powder dry and fit in yur patchbox???
