manufacturers of old never put a small fuse in the rx right after the input
jack, just in case?

 ==============================

Not necessary to add anything to the interior circuitry.

Back in that era the common thing to do was connect a NE-2 across the
external antenna terminals (that's what I did 50+ years ago) or if you want
to be modern, put back to back silicon diodes across the antenna terminals.
This applies to a rx with a terminal strip for the antenna connection.
