The first one is a BNC Connector w/ Chasis, the one in the middle is a XLR 5-pin female socket connector (which I have), The third one appears to be a quick-disconnect, but I cannot seem to locate the correct model of the BNC or the quick-Disconnect.

Also I am looking for this:

Could this be the reverse side of a BNC connector?

The one on the left is called "BNC" and is still common. Used on high end video, test equipment etc...

The one on the right is quite indistinct, and the second picture is even worse.

I agree 100%, however finding the BNC female connector with the base mount is proving difficult.

The knob in the second picture has a kurled tip and either pushes in (like a button) and/or twists like a volume adjustment. Maybe a potentiometer?

Do you mean it functions like the quick-disconnect on air hoses? Push in the collar to release the connection?

What exactly are you working on, if you don't mind me asking?

the small thing looks something like this:

I believe it works more like a volume control knob, but I am speculating.

I am to relocate these connectors that where on this custom unit, but have broken and/or come loose and vanished over the years.
