[ARC5] Expert knowledge needed

[Paul Redlich Tri-State Warbird Museum]

Can anyone identify the function of a BC-767?  It's called out in the radio
installation of our 1943 Curtiss P-40M aircraft as an "indicator". To the
best of my knowledge it had something to do with the destructor used to
destroy the IFF radio gear installed in the rear fuselage in the event of a
crash landing behind enemy lines and may have been purposely misidentified
in the blueprints to prevent enemy espionage of the IFF technology. I know
this occurred as the "destructor" (explosive device installed in the
fuselage is identified as "fire extinguisher crash switch" and the pilot's
manual does not refer to the IFF set other than to call it "a supplemental
communication radio".

Any help would be greatly appreciated!
