RazorEmporium's Gillette date code site says that these razors were in production in 1971: TTO, Tech, Knack, and Trac II. I'd like more information about which TTO models were made then. I know there was a Flair Tip Super Speed, but I'm not sure if it came in any variations in 1971. I think there were adjustables too, but I'm not sure which.
Can anyone shed light on this or suggest another site?
