Is it still connected to the carbon track, or has it broken off of the insulator that the track is deposited on?
Do you mean that you can't find where the lug was connected to the pot, or can't find where it was connected to the radio wiring?
Is the "metal ring" a ground lug that is around the pot shaft that connects the lug to ground when the pot is mounted through a hole in the chassis?
Sorry for all the questions, but it is difficult to tell from the pictures/description what is happening here.

Here is a pix of a common pot...in this case the lugs attach to the fan shaped insulator with bent over tabs...sometimes small rivets are used.
I have labeled the lugs "A B & C"... perhaps some ohm meter checks between A & B and then B & C while the shaft is rotated would reveal proper (or improper) operation of the pot.
hope this helps,
