Aircraft (?) Fire Warning and Control Panel

Cool toy found at an antique shop this week. It appears to be an aircraft fire warning/fire suppression/overheat warning control panel.

It screams "Mil-Spec", but I haven't found any labels or tags inside or out. The inside is just basically wires from the switches and lights connecting to a big cannon plug in the back.

It's obviously set up for a twin engine vehicle, so I'm thinking DC-3 (Tom Solinski?), C-47, B-25, B-26, A-26, etc. However, the rear case is thin fiberglass, not metal. Not something I would have expected during the war.

I keep saying "appears", because I'm not truly sure it's for an aircraft. It's too lightweight for a boat or military vehicle, though.

Bottom has printing:
89257 502 ASSY
NO SHORTAGES
...with several QA stamps. With big "N"s...North American? Northrup?

Back has printed, under the Cannon jack:
REF: SERVICE DIAGRAM
NO.30.0200 EREC AND
MAINT. MANUAL

Anybody got a good guess?

Edit: Occurred to me that it MIGHT be for a helicopter....

Cage Code 89257 is the Hammerblow Corp. They do both US and Canadian parts. The notation of 30.0200 screams Canadian or Brit.

Cool! Thanks! I'll start looking in that direction.

It is the panel from an Northrop F-89 Scorpion.

You can see it just to the right of where the pilot's knee knows in the picture (and above the red strap).

Many thanks, Ron. As I posted on POA, your answer was a joyous link to my past. I got interested in aviation because of the F-89s flown by the local National Guard unit.
