Please help me date my Gillette

[Bird-Man]

I've got a Flare Tip Superspeed with the date code Z3. I am selling it over in the BST but I really am not sure what date it it. According to the Dating chart in the Wiki it is either a '54 or a '79. I want to think it is a '79 when I look at the chart but at the same time when I look at the Superspeed article in the Wiki it says that the Flare Tip Superspeed was only manufactured from 1954-1968. Any super knowledgeable members out there with insight to help my dilemma?

My first thought is 1954.

[Zephyr]

The flare tip superspeed was produced from 1954-1966, so yours would be a 54.

Super-speed production likely ended in 1974. Yours must be a '54.

Yours is definitely a '54. See my Super Speed Identification thread for more info.
