@Oculus:
The ground leads I found have a thread outer diameter of approximately 3.35mm.
They are definitely from vintage Tek probes and were intended to connect with the tread to threaded crocodile clips. The other side is a spring clip which did go around the probe body.
But there is one with two threads, so I guess they are the same.
I could spare two of them, which you could adapt by fitting a croc or a 0.64mm for the mini-grabbers used now.
Send PM with adress/answer.
