Afternoon, Mike.

From the ends, up close, it is just a form of 1940’s ‘plastic’ sleeve. The jumpers are solid tinned copper leads and I think these black sleeves were just an added insurance against the leads shorting against the chassis behind the panel, as a possible result of any misadventure the receiver might be involved in.

They are slightly loose on the leads but for the most part do not move easily due to these leads having been drawn in rather close to the back of the panel when soldered in place.

So basically just the solid lead and the sleeve, Mike.

Best regards,

David
