This item was in my families home in the food storage pantry. We have had several generations since 1951 live in the home and most are now passed on. We have no idea what this is for.

It is a combination oscilloscope and Vacuum Tube Voltmeter (VTVM) Most likely a kit to be built in taking an electronics course with DeVry.

It is a useful service instrument, but these are usually entry level grade and only have basic functions.

Did a family member take an electronics course with DeVry at some point?

That is a combination VTVM (vacuum tube voltmeter) and oscilloscope.

EDIT: Steve beat me to it!

DeVry alumnus here (‘64).

I would just add that, before you move the unit around much, the “picture tube” needs to be put back into place so the front is supported in the front panel. Otherwise its neck may get broken.

It’s a nice old piece that I’ve not seen before.

It is a cool piece as you don't usually see two pieces of equipment merged together like this.

They are related as a scope is a fancy VTVM, especially one that has a calibrated vertical input with so many volts per division.
Since this lacks that ability, the voltmeter makes up for it. :D

I don't know if anyone ever took an electronics course. I also don't know what to do with this.

Because it's unlikely anyone would actually use that today, it has more interest as a rather unique display piece. It doesn't have much actual value, the sentimental value of having something that was built as a kit by a family member would be significant.

Otherwise, if you need to sell it you could start by putting it on your local Facebook Marketplace, or Craigslist asking a nominal price like $25 and see if there is anyone interested. Be willing to negotiate downward if there is anyone who shows interest.

I would also suggest placing a for sale ad here, in the classified forum. There's no cost, and you have a small but focused group of instrument collectors to appeal to.
