From the page quoted above "Ralph Lauren Lines, And 'Who Makes What' - A Definitive Guide" :
PRL with 'Ralph Lauren' in script, followed by "Made In England" - Edward Green
PRL with 'Ralph Lauren' in block letters, followed by "Made in England" - Crockett & Jones
RLPL 'Made in England' - Edward Green
Can someone explain me why the would be C&J, what am I missing?
