From the pin set out they are grouped
There is a space between the 2 groups
2 on top 4 on bottom. Pins 1 & 2 (3) 6,7,8,9 Block 2# 3 (4) (5) to 10,11,12
Pins 1,2,3 & 5 have been connected solder used... bottom bank 7,8,9, -- 11,12
also 13 071 collates to the pins maybe a red herring.
This to me looks like the layout for controlled
Oscillator. Input at top and frequency are at the
Bottom . There well could be an old type cat's hair Crystal's OA81 and coils .
They will give these odd measurement . I think it's an old receiver home made. The 2 bottom pins with zero are the ground and plain or Arial . With a cap isolated. .
Make measurements with a signal gen start low 230hz on the to top measure at lower block
The number on the top is the wave length.
Your drawing did not make sense as all resistance. The low values are probably coils And the cap are not showing nor are the oscillators...
Also the box is hermetically sealed for a good reason . other wise it would have been screwed down.
There maybe an Old Vacuum tube that would also account for the light weight the post war tubes were in
Metal cans . 90v grid 6.3v heater. if it is an oscillator tube it will have a low heater voltage .
Have not see one for over 50++ years
You will have to use all your resources. on this one . But its Not a resistance Box .
But solve 1 block, first left top and the bottom 4 .
