Tool ID Help Needed

[RustyNailSalvage]

Hey guys, I acquired a toolbox at an estate sale a while back. The guy was a big-rig driver and had all sorts of stuff in the box. I am having trouble identifying a pair of tools. They look to possibly be some sort of die?

Looks like a large tap. It definitely hooks to some sort of ratcheting device. You can see the detent balls on the side. What size is it? Looks like 3/4" to me?

Both have a 13/16 head on them. One of the thread openings is larger than the other.

Looks like a spark plug thread chaser 14 and 18 mm size with an adjustable stop. Just a guess

You know, that kind of makes sense Bigshed. I just Googled "Spark Plug Thread Chaser" and found something that looks just like these. Good call!
