The RCA Victor 47 Prefix Series – Popular Mono
The beginning of the 47 series is a bit perplexing. The 47-0000-47-1999 series was designated for childrens records but RCA Victor didn't use many numbers. The 47-1000 series was skipped completely and the 47-2000 popular mono series starts at 47-2715 with a reissue of a 78 originally released in July of 1941.
With the introduction of the 45 was also the introduction of the 45 box set, which consisted of multiple 45s creating an “album”. The 45 box set numbers are a continuation of the numbering system used for 78 albums with a “W” added in front of the “P” (Popular) used on the 78 albums. Generally the box sets consisted of three 45s and used the same graphics RCA Victor had used on the 78 album. Because most 78 albums consisted of four records, some 45s in box sets will appear to have no 78 equivalent. Generally RCA Victor, in making a 45 box set, issued 45s of the first two 78s in an album and the third 45 consisted of one side from each of the remaining two 78s. RCA Victor box sets are indicated by a number starting with “WP” which will be above the 47 prefix number. By the end of 1951 45 box sets were phased out and replaced with Extended Play records (EPs).
Also at the end of 1951 RCA Victor ended the
48 prefix series (Country
Western) and 50 prefix series (Rhythm and Blues) and those recording
were released from then on in the 47 prefix series.
The 47 prefix series ended in 1971 with the
release of 47-9999 by Dolly Parton. By then the 47 popular mono series
was overlapping the 74 prefix series of popular stereo. The 47 popular
mono series briefly continued as a continuation of the 48 prefix, which
had ended at 48-0501 in 1951, with mostly Country Western 45s beginning
