Assuming the picture appears, my dad gave me these three parts. I do not know if they go together. The only reason I am asking here is that he gave them to me at the same time as a shotgun cleaning kit and the middle one looks like a small rifle brush.
I have no clues on the others.

Not quite sure what the two things on the left are. Cleaning jags?

The middle thing is definitely a brush. Does it have a caliber/bore stamped on it?

What is the thing on the right? Some sort of telescoping cleaning rod?

Yep, you're gonna need them...

Wow... That was enlighting

Not sure what the items on the left are. But the brush is definately a bore brush (not sure of the size). And if I'm not mistaken, I think the thing on the right is a generator for a coleman liquid fuel lantern.

the one on the right looks like a cleaning jag as well, looks like maybe the tip is bent.

Not sure, but the two items on the left look like line leveling cams for a bait casting reel.

The one on the right kinda looks like something off a Coleman lantern ....

middle is a brush of course

left side items.. .not a reasonable clue

My best quest are: Left are leveling cams for a bait caster old style langley or bronson perhaps? middle is a 22 rifle cleaning brush and the left is off a coleman pump-up mechanizm for lantern and or cook stove I believe?

Right is a thermocoupler for you heater.
