Try sourcing an old oscilloscope from a college physics department. I think that is what is there.
The smaller unit on top is an old water temperature device that used a wire sender.
I think it was called an XBT. Try NMFS or WHOI in Woods Hole, MA. They may have some around, or a faculty or staff member might too.
It looks like he’s rigged up a fish finder, the signal generators sends out pulses at around 200 kHz, the scope shows the echo from either the bottom or from some fish when there’s a shorter return delay. I’m sorry I don’t have either of these units, but it looks like they can be had on ebay for around $100 each.
Lou and Halsey,
I have a very similar looking unit to the upper unit (old water temperature meter)
that you can have for free. Where do I send it? I found it at work today.

Top Photo looks like a signal generator, maybe a Starkit LSG-10A like this one:

Below it is some kind of vintage oscilloscope, maybe a Sencore PS148A like this one:

Of course, the beer can should be easy to get from http://www.narragansettbeer.com
Not sure what that is in the bottom photo though, maybe a welder?
That looks like an oscilloscope (with round green screen) and some kind of a meter atop it.
These look like BS props.
