Nick,
That looks similar to the Lectrascan, but it's not the same as the ones
that were used in stockbroker offices. They had two rows of tubes.
Here's a B-A catalog illustration from 1976:

Scroll to the bottom of this page to see a complete Lectrascan unit and
a module as the B-A catalog shows.

Pretty sure this is a B7971-based display, though not 100% certain -
I've not seen this photo before.
There are plenty of "distant" photos of such displays, but I've not seen
one like this in close-up...
Thoughts?
