Identifying film stock question

[DavidBradley]

I'm currently transferring home movies from the 1930s through the 1970s for a client.

We're trying to put the films into some sort of order.

The 8mm films from the 1930s are easy to identify the date codes on.

The Super 8 films from the 1960s and 1970s have proven to be a challenge. First, the date codes are so small that I'm not able to read them with the naked eye. I tried a magnifying lens, and that wasn't strong enough. I put them on a transparency scanner and scanned them at 4800 DPI and the resulting image is perfect for reading them. For the Kodachrome films he has, this has proven very useful. However, there are some films this isn't helping me with. I've encountered a set of films that are color film with no visible edge codes. Upon running them very slowly over a light source, I've found there are some places where there's some letting on the edge and have scanned that section to see what it says. What I came up with is different from the Kodak codes. The Kodak codes appear to all be clear on a background of black and clearly give the Kodachrome IIA and date code and the word SAFETY. This batch of films ONLY has the word SAFETY. I can't find anything else in the sprocket area of these reels. The word is not clearly transparent, either, it's brown against the black film. It's a sans serif font, all caps, with the letters SA, a sprocket hole, the letters FE, a sprocket hole, and the letters TY.

Is this a Kodak film? Is this some other known manufacturer? (I can't find any descriptions on the net for any manufacturer only using the word SAFETY and nothing else.)

Any idea when this particular film may have been manufactured and how I can approximate the year?

Any information would help.

Thanks for your time.
