9737 COPO
I got to thinking after reading another thread,what does 9737 (the number not the code)stand for?I thought it would be a COPO code number issued from a numerical count of preceeding COPO's.This does not explain the 9560 and 9561 codes of 1969 since 9737 was around in 1968.The 9 seems pretty consistant throughout the years,was this a prefix code for the COPO projects or just a chance digit.The other RPO codes seem pretty common,lettered A-Z and continued thru the years.Not a very significant question but it has always made me wonder...........
