Help What year and what exactly are these tune up tools??

I have some WAGs.

Is the "dial a gap" flat like a screwdriver? If so, maybe it's for setting point gap from closed to the proper setting, and the marks on the "drum" would be thousandths of an inch. I'd venture to guess that this tool was used for '55 and '56 distributor point setting, to help avoid repeated removal and replacement of the cap, because V-8 GM engines didn't get the cap with the "window" until '57.

As for the "wrench", if the blade labeled "spark plug" is .035" thick, it's a plug gap gage. If the blade labeled "distributor" is .017" thick, it's for gapping the points. No idea what the open-end wrench part is for.

Do I get a prize?

Looks like the distributor hold down bolt/nut. WAG here as well.

OK, that could be. It sure wasn't for a spark plug, and 9/16" is about right, by the looks of it.

You better guess than me.
