Snapon impact nut drivers

[Bunit98]

Hello, I have these snapon impact nut drivers but do not know what there worth or where they were used for

The one on the left is a 7/16 with a part number(gm 3042a on 1/4 driver) and (gm 14b on socket)
The one on the right is a 3/8 with a part number(gm 3042a on 1/4 driver) and (gm 12b on sockets)

If anyone know when they were made or there value it would be greatly appreciated.

Funny I just remembered when reading this that I posted a GM 3042 a while back. It didn't have Snap On on it, just the part #. You ought be able to remove the sockets if you poke the lock button inside the little hole.

Those look like old power drivers, not impact.

You have maybe $15-$20 there total.

Two 1/4" sockets, two 1/4 hex to square adapters.
