Can anybody help me with identification ?

Hello, please can you help me with identification of this part ? Is possible from Consolidated Liberator B 24. Thank you for yor help !

Looks like a radio system plug to me - many of them have the PL prefix and the pin socket inside supports this

My suggestion would be to ask on an avionics site like
BAMA The Boat Anchor Manuals Archive (old radios are known as boat anchors and the technicians who fit them are often called ballast fitters.
or
radionerds.com (Chris Story)

As a last resort you could try an email to usarmy.APG.cecom.mbx.cecom-lcmc-historian-cecom-lcmc-dcsops@mail.mil

Great people and very helpful with documents but unless one of them knows the exact equipment it comes off they probably cannot help.

I also know there is a manual that has pictures of all the various plugs but it is years since I saw a copy so I cannot remember the title

Happy hunting

Once you identify the radio get hold of a copy of Technical Order 52b-43-01 Airborne Radio Equipment Handbook and that will tell you what aircraft that equipment is fitted to
