I found this , well actually two of them over the weekend buried together in decades of leaf mould behind a former aircraft dispersal pan. One is clearly marked 1943, and on this example sadly the date of manufacture is illegible.
My question is what is the significance of the stencilled markings on the side? A serial number for the batteries charging schedule or related to the individual aircraft it was fitted in?
Over to you..

Not sure about the markings but I think that they may have been used in the TR9 series of wireless sets.
I recently picked one up at an auction house with an R1155A, so may also have been used with them. No idea about the stencils though. Good find !

Ah so that’s what they looked like.
Some of those black and red knobs (neg and pos) we found during the recovery of Whitley N1521.
It crashed in january 1941.
