This photo appears on page 240 of the 1963 MIT yearbook, and appears to be a picture of an undergraduate teaching laboratory. Notable is the method of showing the time and voltage settings. There was a hole in the front panel above the knob and the sensitivity was shown through a back-lit dial. The scope was tan in color with dark brown features.
Several people have suggested that the brand name was "Analogic", but the present-day Analogic Corporation did not exist until 1967.
Does anybody recognize this scope?

Interesting. Also note the number of graticule lines.
Not sure of the model number (400-series, IIRC), but it definitely looks like a DuMont scope I had many years ago.
My unit had an orange CRT filter and P7 long persistence phosphor.
Ouch! Scopes in danger to go outdated because of their OS! TEK is very likely not the only manufacturer facing this issue. (At least, Le Croy comes to mind, too.)
Sorry, off topic in the strictest sense, posting this as a comment to your most recent Scope Sunday.
A little late for the party here. I realize this is an old post, the scope you refer to is an: "Analab" dual trace scope type 1120
Even later to the party here. I once salvaged an 1120 from a lab at MIT. For all I know, it could've been the actual unit shown in Kent's photo. It was a slow and heavy beast, and did not stay with me through the move to California.
Very little about Analab Instruments appears on the web. There is a reference to EDVAC and a model 1100 scope, from 1949, and a photo or two here and there. But that's about it.
I had one of those that was surplussed from NASA Langley in the 1970's. It was a great scope probably 100KHz bandwidth and would go down to 100uV IIRC. Sadly, the HV transformer failed and since I was in high school at the time I could not afford to get a replacement. Later I got a HP1200A (I still have it) that was surplussed from a company I worked for after college. Too little time. Too many scopes.

I too am late to the party but I know what this scope is. It is an Analab probably an 1120 model. They were beautiful scopes.
