[78-L] RCA Prefix Code

And from way back in 2001, here's J. E. Knox's quickie version of the 50s and 
60s system for LP prefixes:

E0 through E4 = 1950-54 [that's E-zero, of course, not E-OH]
F = 1955
G = 1956
H = 1957
J = 1958 ('I' not used)
K = 1959
L = 1960
M = 1961
N = 1962
P = 1963 ('O' not used)
R = 1964 ('Q' not used)
S = 1965
T = 1966
U = 1967
W = 1968 ('V' not used)
X = 1969
Z = 1970
A = 1971 (letters wrap around here; not to confuse with A = 1920s, which 
actually WAS done in the 1940s on certain reissues!)
B = 1972

Somewhere around '73 or so the whole system changes again, whereby the "matrix 
number" becomes the catalog number or some such. But it's not on 78s, so who 
cares?   :-S
