Thread: J.A. Henckels Twin Works lot 7? Aging Help?

I'm wondering if anyone can help me narrow down the age of this razor. It's my impression that the number above the logo is the "lot number", and the guide shows this version of the logo is 1900. so it's somewhere between 1900 and 1969. Anyone know how to find the exact age or close to? And what does the number mean?

Thanks everybody!

I looked up Graef & Schmidt in my Goins Encyclopedia and came up with a date range on them between 1881-1952. If I were to "guess", I would say 1940-1952. I think the grind is more "modern" before using & making straights faded away.

No matter, that's a great looking razor that most anyone would enjoy having in their rotation. Should make a great shaver once properly honed. Yours truly, Scott

Graef and Schmidt were distributors of J.A. Henckels since 1885.
From one source Graef and Schmidt became the Welkut Company in 1952, from another source in 1943.

And what does the number mean?

Model/cataloge number.

Thank you!
Yeah, i had it honed and polished up a little recently. It works really well!
This is my first straight razor, and I think they're incredibly fascinating

where do i find that information? is there a detailed guide i can download?

I have the "Goins' Encyclopedia of Cutlery Markings". I think I bought it off Amazon.
