I can’t say when your Proto box was made but I know for sure that the Proto logo was used at the Beach / Stanley plant shortly after Stanley acquired Beach in 1987.
The Proto boxes I’ve seen were not built any better than others with different logos.
The tooling and materials were the same.
Here you go, Tom. Beach made so many models through the years,constantly changing & updating.
With no date stamp on any, its not possible to pinpoint exactly when it was manufactured.
No, the Beach boxes had no date code . I would guess its late 70’s, early 80’s.
Newer versions had extruded aluminum drawer pulls.
Yours is sure in immaculate shape!
No, Stanley acquired Beach in 1987 when the plant was booming & the owner was retiring
so they didn’t “rescue” the plant.
I’m sure policies & opinions vary on each plant site as with any large corporation but as a former Stanley employee long before they closed the plant I worked at, I can say...
Agreed. Stanley has a long history of treating employees like ****. They are the bottom of the barrel . Most of their modern day tools are **** anyway & easy to avoid.
Here is a good read on the history of Beach Industries , the sale to Stanley Tools & their demise.

On furthur review I dug through 100 years of crud & did find the 5/16-18 tapped hole you described in the Ball of the main screw. Though the spring & set screw were long gone, running a tap through & adding new spring & set screw made it as good as new. Thanks!
