Need Help With Gunsight (CA-505)

[CaptainFig]

I have a CA-505 Gunsight that I would like to put on display and power up.

In the 1980s I flew T 33's in Alaska and while there we reactivated the bombing circuitry and used these 0-2 gunsights. The gunsight I have was saved from the salvage yard when we retired our last Shooting Stars. This memento obviously has great meaning to me.

The gunsight obviously uses 28 V DC and has four wires. I could experiment with powering it up but I was wondering if anyone has any knowledge of the proper connections or an electrical schematic for this item.

I would be very grateful for any help anyone can offer.

Thank you very much, Capt. Fig
