I ask the forum's help in restoring this tool to its former greatness.
I have more than a few T-bevels with this style of fastener.

But this earlier example is missing a nut of some kind (appears to be 1/4-20) and I'm wondering exactly what it should look like and if it's brass.

Thanks in advance for any light you can shed on this.
