I've found a listing of the work being issued
on a 4-LP Westminster set WST-300, but can't
confirm this - also do not recognize this series.
(There was an early WAL -xxx series).
The recorded work (from French VEGA, recorded 1957) was issued on 3-LP
Westminster OPW-1304, and reissued on Westminster Gold WSGO-8173-3.
Can anyone confirm the 4-LP set????? Scan ???
