[Test-Equipment] Identify antique test gear

[Dave]

Bob;

Memories! Walking Morgans old route across the Isthmus of Panama in the 
early '60s with one of those. Found some artifacts on the hike.

Do you have the early or late "M Scope" manual? I have the early one 
using tubes. If yours is that old I would like to get a copy of the manual.

Can be used to inductively couple the signal to the pipe or cable via the antenna (the metal strip around the case) or you can connect directly to the cable/pipe. (I use it inductively).  If I can answer any questions, just ask.
