[78-L] Columbia 1950s demo

[Royal Pemberton]

Columbia marketed some  phonographs in the late 1950s/early 1960s with names
like the Masterwork 360.  AFAIK at least one model was a rebranded Pye
product.

41662 as a Columbia catalogue number for a single would have dated to
approximately late 1960 or some time into 1961, so well after 78s were
discontinued in the US and Canada.  It is an LP, and that is what the matrix
number of 10" microgroove (mono) LP records was, LP, so the matrix number
properly is LP 41662 which would place it circa 1957.  (The X, as in XLP for
comparable 12" LPs, was a throwback to the Brunswick method of adding the X
to the matrix prefix to denote 12" items.)
