cabinet~milk shake

[Barnhart]

Allan Metcalf in _How We Talk_ mentions _cabinet_ (for milk shake) but
without dates.  Mencken, OEDs, OEDas, DAE, DA, HDAS, Dict. of Am.
Slang, and Am. Dialect Dict. do not have an entry for this sense of
_cabinet_.  DARE has a citation for 1957, but not earlier.  A friend of
my (born about 1944) from Rhode Island recalls them from his youth.
Does anyone have earlier evidence?
