Agree, seems to be a home made timer of some sort. The case is very similar to one I have that I got from Radio Shack (long, long time ago)
The board seems to have 4 sets of timer circuits of some sort, matching the 4 position switch in front. The push buttons and toggle switch seem to be typical Radio Shack products as well... The stud mounted device on the back panel seems to be a SCR type of device... Transformer on the power supply board is a typical Radio Shack transformer...

The inside view does not show the back side of either the rotary switch nor the 4 digit thumbwheel switch that we see on the front panel. although it does show the toggle switch. I find that rather confusing.
From the markings on the controls the indication would be a presettable timer device with 4 ranges, but looking at the inside it does not appear to be that sort of device.
So from what I can see it is a usable case with some potentially useful components. With pictures that show what we don't see now, and the type numbers off those IC devices we can provide more useful guesses.

It's a Multifunction Timer. Just guessing!
Here's a newer one w/ 0-999.0 min 0-99 /59 sec and so forth

No, it is NOT a multifunction timer because there is no function switch, only a 4 position range switch. two controls, start and reset. And that is not a guess. Two transformers inside is a bit of a puzzle, although it may be that a whole lot has not been shown to us. I did not see any wires coming from that 4 decade thumb wheel switch assembly, so who knows?

There appear to be ribbon cables running up to the thumbwheels, it runs to the side mounted board which has a largish DIP package on it. The secondary PS board seems to be providing (up to) ~6V to the 3.5mm jack on the rear panel.

In general, the layout and wiring are quite untidy. If it isn't a homemade device for informal use, it's very poorly constructed indeed.
