What is it?

Daryl--maybe the slots were to align a shaft with a keyway and key to mill a flat or another keyway on opposite side of shaft---looks useful for many different projects ---tools are always handy to hang onto even if you don't know the intended use-----Dave

What field was he in?

My Uncle was a tool and die maker for Tennent. They make floor sweepers.
He tells me that my grandfather was a lathe man for FMC / Northern Pump. Which made submarines.

Are the slots such that a mounting bolt head would be below the surface? If so I really could have used something like that to work on a buggered gib I had. Would also come in handy for cutting the eyebrow relief I cut in the same gib for some quick locks I added to it.

Would help to know what he did there as it might have been something very proprietary to the equipment.

There is no shoulder. Just straight through.
But the gib idea is helpful as I need to make a gib for my VN22.

That make sense. Especially if they had production.
I have no intention of letting her go!!
