What are these??!!

[badchihuahua]

Found these tools in an old barn. Any ideas as to what they are and what they were used for? There is writing on top of the round metal part that reads, "Rainbow for 1/2" outlet." It also says HT -2 or H7-2. Thank you!

I think they are old wood burning tools or leather working.

Are all the tips the same or are there slight differences?

Thank you. I looked up leather working and didn't see anything like these. That gives me a good starting point to start researching though!

I'm thinking some sort of soldering irons, although the shafts are on the short side.

You are correct on soldering iron. This one says for canning but could have other uses

I have several of the old soldering "irons". All the tips are bronze or brass.

They do look very similar. Thank you!
