Optikleen (Kleer-view) washer solvent color
 

What is '65 solvent color? BLUE is the accepted color for the Optikleen (Kleer-View was the dealer accessory version)in the triangular shaped bottle at least after 1969 - I have a factory photo clearly showing it. An old time Chev dealer recently told me he remembers it being GREEN prior to 1967-8 or so. Anyone have any evidence??

Also, anyone have a confirmed 1965 bottle label? I believe the repro is a much later version.
Thanks
Dave
