This one is annoying me - It has a Douglas inspectors stamp and part number and was found on a USAAF base but the part number does not match any item in the C47, C54 or DC3 parts lists.
767-400 and 35
The bulbs are too small for IFF lights and the rod is just confusing as the end has a screw in it and no wires to it or through it.
The shaped piece the rod sits into is specifically made but also roughly welded on.
The screws are brass.
the text in the box underneath is aged but looks like:
MT-133/ASS1
NO as 2629:COA
Any suggestions would be greatly appreciated.
