[Milsurplus] Need: LM-13 freq meter power connector pinout or entire schematic

[C Eus]

All:
I am in the process of converting this LM-13 into a VFO.  Since she's
missing the calibrated "book," I don't mind turning her into something more
useful, I figured I should use the schematic from the 1947 March QST edition
schematic to make this happen. However,  I do not know what the pinout is on
this unit.  Luckily, a previoius owner elected to keep the original plug
with the LM so I won't have to fiddle with making a new connection.  But
just the same, does anyone have documentation? Thanks. Cal, n6KYR/4.
