Date of manufacture request

[Lacamaslake]

Can someone date a True Temper double bit “4” (swamping pattern) manufactured by Kelly Axe and Tool Works in Charleston W. Virginia?

Quite sure you'll get a satisfactory answer on here but understand that a single picture is worth a thousand words.

Are there ridges in the eye?

Thanks for responding! There are no ridges in the eye. It is smooth.

THE AXE has True Temper engraved on one side as well as a large 4. On the other side is KELLY AXE & TOOL WORK CHARLESTON, W. VA. USA. There are no ridges of any kind in the eye. Measures 11.25” x 4.5”. The center is is 2.75” high and the width is approximately 7/8”.
I hope this info helps in the identification and age.

Some clues:
True Temper's patent for the eye ridges was Patent Number 3090653, filed 7/2/59 and granted 5/21/63.
If the specific axe model isn't shown in the 1957 catalog, I'd surmise that it was manufactured sometime between 1938 and 1957, since I don't recall any evidence that Kelly axes stamped "True Temper" were being made before then.

Thank you very much!! Catalog is very helpful. Now I am trying to determine if it is a Young, Humboldt or a Swamping. Difficult to identify model. Inclined to think it is a Young or Humboldt and not the Swamping from 1938 catalog pictures. Thank for the help! Lacamaslake
