Need help identifying wrench

Does anyone know which engines this particular wrench went with and what are the two centre (hex) cutouts for?

Maybe one of the RC engines that came with glow plug conversion? I have one such wrench. The standard plug fits the smaller cutout and the Nelson plug fits the large.( Though I am not sure if COX really adapted its accessories to 3rd party tune ups like Galbreath head and Nelson plug?)

That plug is on the TD RC .09 but it's a .049 wrench.

Bernie the semi-circle end cutout fits the 09 RC plug conversion head:

.

The other end is really for 049 size exhaust port though.

That is true but the wrench part # is 1530; which is the same part # as other .049 wrenches, so it was likely designed with .049 in mind.

The are similar to the 50's and 60's wrenches but silver and with the extra cutout on one side.

Prop nut on Thermal Hopper seems to fit one of the cutouts. The other remains a puzzle.

I believe those wrenches were included with the mid 60's cars such as the Corvette Sting Ray, Buick Riviera, and Ford GT. One of the hexagonal openings was for the flywheel nut.
