[Boatanchors] Filter ID

[Jack Antonio]

This is probably a long shot, but here goes.

I wound up with a pair of SSB filters, the only markings
sre a part number, and whether they are USB or LSB.

They are in a hermetically sealed can, about 2 3/4" long
by 7/8" high, by 7/8" wide.

The part numbers are 97476 for the USB filter and 97477
for the LSB filter.

A quick pass with signal gen and scope shows that they
are in the 455 kc region, and one of them is bad.

Anyone recognize these, as to what kind of radio they came
out of?

Thanks
