Philco 39-30 restoration

[Nick_the_'Nole]

Never seen those shims on a Philco before, but it's curious how they happen to be almost perfect in length for that chassis.

It looks to me like they're about 1/2" too short for the full length of the chassis, and about 1/2 - 3/4" too long to fit between the rubber pads.

This is just a guess, but I'd say they were factory equipment, just on a different radio. Just judging by similar systems I've seen in the past, I'd suspect their original purpose was to work as a guide for reinstalling a chassis... they were probably secured to the interior bottom of the cabinet in some way, maybe in a recessed channel, and the matching chassis would have had some sort of nuts or bushings along the bottom edge that would have slid in between the forks and provided a quick and easy way to line up the screw holes.
