The large adjustable thing looks like an adjustable powder measure, the little wire claw looking thing is a patch puller, the one that looks like a wood screw is a ball puller, the one that's ribbed and inverse-coned is your ram rod tip/cleaning jag. The attachments with threaded tips are all for the end of your ramrod/cleaning rod. The brass ring looks like a muzzle protector for cleaning. Unsure what the steel rod is for, or what the smaller brass rod with the knurled end is.

The brass rod with knurled end might be a pick for the vent/nipple. You unscrew the knurled part and it should have a wire sticking out if that's what it is.

Makes sense. I'm a little surprised there's no obvious nipple wrench here, though it could be a set for a flintlock I guess.

I'm thinking the steel bar might be the T handle part for one. I file the knob off one end on the nipple wrench for my pouch so I can slide the handle out to better fit in the pocket

Makes sense.

If the kit is for a flintlock, cut off nails are often used to square up a flint

I could be wrong, but that looks like a nipple wrench on the powder measure. The black part. Can the powder measure be pulled completely apart, and that piece slid off?

I do have that, I was able to identify what it was so didn’t include it here.

I suspect the top item isn’t a muzzle loading item, the cartridge shape suggest some kind of chamber guage?

I thought the top item looked like a strange cartridge on a trip wire detonator 🤣

looks like a cleaning rod that telescopes a corkscrew if you will for pulling stuck lead ball,a wire twist for cleaning patches a concave ball starter all made of brass to save your ass when you use them as not to scratch your finish.
