Diamond "T" ,"T" Diamond tools. Who made them?

[Snaparxon]

After the brief discussion here,Who made me? I was inspired to make the 3 hour round trip and go get what I had seen the previous week-end. There is not much, if any knowledge out there as to who used the diamond and a "T" to mark their tools. I ended up finding some tools in question as well as a couple P&C, and a few unmarked that are similar? I am trying to decipher what is what in the pictures I took(95) and will post side by side etc. if I just don't start over so it is fresh in my mind.

Here are the Diamond "T" tools


The two I found used a 1/2" hex drive rather than a 1/2" square. That is the hex you see in the pictures.

This one ( diamond t ) has a almost brace-bit looking 4-sided shape and the socket is pinned.

Here are the P&C

Here are the unmarked tools

Here they all are side by side, left to right, unmarked, unmarked, P&C, Diamond T and Diamond T

There are some similarities, some differences. All made by one company? P&C, very early Thorsen , made for a contract by P&C?




Next is Diamond T on top and P&C on the bottom


Top to bottom, Diamond T, P&C, unmarked and unmarked

Wow, devotion to the research, I love it

Oh hell I thought you meant the trucks.

Sorry man, added tools to the title to eliminate confusion.
