Has Anyone Heard of the Natco Company from the 1950's?

I picked up an interesting looking vintage piece today that I'd like to convert into a guitar amp. It's a 1956 (I think) Natco film projector amplifier. The stock speaker is a Jensen Alnico 5, and it has a nice big power transformer. The GE tubes appear to be original - they lit up fine when I plugged the amp in, although it's hard wired for the projector input, so I had to roll the dice on it.

I haven't found any forums where this unit is being talked about - just wondering if anyone has heard of it. I'm guessing I should be able to get a decent sounding amp after I've modified the circuit for guitar.

Nice score mate, Are the power tubes 2A3?
