[Milsurplus] Sorta off topic question

[Richard Brunner]

Here's another one.
I have an RMCA AR-8506-B receiver from a WWII Liberty ship, with a
yellow metal tag on front marked:

USA
LIB-44-234

"44" matches the 1944 date on the nameplate, but 234 does not compute.
If it were hull number it would be at least 1800 by 1944.  The s/n on
the receiver is 44585, which doesn't relate either.  Any clues?  It
would be nice to have provenance on this receiver.
