2\$\begingroup\$ It looks like a high power coax fitting - might be used for a broadcast transmitter output to antenna feed line. \$\endgroup\$– Peter BennettCommented Nov 9, 2022 at 0:30

\$\begingroup\$ Can you provide some context such as where you got it and what equipment was near that it may be associated with. \$\endgroup\$– BarryCommented Nov 9, 2022 at 0:31

\$\begingroup\$ I think Peter Bennet is close, especially given the RCA symbol on the side. They were big into radio and TV transmission (and reception) way back when. \$\endgroup\$– SteveShCommented Nov 9, 2022 at 1:21

It's a rigid coaxial transmission line component (90° elbow, unflanged (copper) for the broadcast industry.
A rigid coaxial transmission line is used to couple a broadcast transmitter to its antenna.
Here's a catalogue of components of another make (American Amplifier Technologies).
