Hi Jeffrey, Thanks for the display interpretation, very much appreciated. I have also found some manuals online which has helped.
This is the thing I bought, it consists of a Tektronix 1711B and 1721 bolted together as a single 19 inch unit. There were a couple on sale, I thought I had picked the better looking of the two, it had the line selection feature but I found when I tried it that I must have accidentally picked up the wrong unit.
Here is another oddity I came away with. its paper backed recording tape. I'll try playing it when I get my ferrograph out.
Best regards, David.
