Weird Calculator?

I just acquired this strange machine; it's a DELTEK 112 calculator that has a 12 tube display.

I found no information on it anywhere online and was hoping someone here might know of it.

1. How did you acquire it?
2. There is no boiler plate info on the other sides?

A guy in a local club got it off eBay and I was tasked with fixing it.

This is literally all it says:

I would definitely bring that into work and just have 000080085000 on it at all times or 8008135

Looks kinda strange with the small zeros.

Apparently this is the one he bought:

No info though

It seems there's a possibility that it's not a "Deltek" per se, but they were an OEM and slapped their name on someone else's shit. Any indicators on the inside that may help?

Nope. It's a beautiful piece inside; solid switches with metal contacts and wires; no ribbon circuits or printed chips.

It's like something you'd expect from a high school science project.
