I don't have the box, but I have the razor. It is a G, and IIRC, they were issued between 1946 and 1955, and cost 66 cents. The only model for the blue handle. I think they came in both gold and chrome.
safetyrazors.net identifies the "66" as a "G4". The "G" series was produced between '46 and '55 so yours would be roughly in the middle of that range as there are eight models in the G-series. Nice find and it should be a good shaver, although a tad more aggressive (which for me is a good thing) than the later injectors.
Cost, not year. 1966 was an overlap between the K series for women and L for men. (safetyrazors.net).
I love my Schick 66 which has textured chrome head like WW's. I don't normally favor more aggressive razors, but the G and E injectors are so dang pretty. (Yes, I'm a shallow, shallow shaver). As mentioned the Schick 66 was the only injector to come with the dark blue handle & its chrome head was atypical for the G (& E types). Here are two ads for the Schick 66-- 1948 Promotional Contest 1949 Print Ad *The letter-typing nomenclature was developed by Alan G. Appleby of safetyrazors.net, not Schick.

I use the chrome 66 that belonged to my Dad. I liked it so much that I was using it more than my Gillettte SA and R89. I got to wondering if there were any adjustable injectors and what do you know, there are! I picked up a nice Schick Adjustable and teamed it up with some Ted Pella coated blades and Tabac soap. Wow
