This Cabin Ancill(ary) Panel likely originated from a Royal Navy Nimrod MR2, but we are not 100% certain due to the lack of results returned when doing searches on the part number. Based on the control and switch descriptions, this panel definitely originated from an aircraft intended for maritime patrol/anti-submarine warfare. On the top row is a toggle switch for mission recording and a guarded toggle for radar reverse. On the next row is an ADS (acoustic detection system?) toggle switch, ADS/TROOP fan Korry switch with indicators, a radar on/off toggle switch, and another Korry switch for the radar fan. The next row contains a locking ADS latch switch with two positions: motor and isolate. After that is an ESM (electronic support measures?) switch, a S/BUOY HOMER (sonobuoy?) switch, and a SONICS on/off toggle switch. Lastly, there is a guarded Korry pushbutton labeled erase. Next to that is just a Korry indicator that illuminates when the ERASE button is pressed. These are arguably the most interesting components of the panel as they indicate the usage of some cryptographic data that was so sensitive in nature that it may need to be erased in the event of an emergency or aircraft capture.

On the back of the panel is a single large twist-lock Deutsch connector. The connector has two different pin sizes. The markings on the back panel unfortunately do not help much to identify this part.

The panel is open on all sides and has a back plate that is secured to the front by some standoffs. This control panel's cable management and labeling is stellar.

All of the switches are sealed with rubber gaskets at every wire entry. Unused openings have small plugs to keep debris out. Most of the switches have date codes from around 1998.

This is the back of the illuminated front panel. It was manufactured by Sirio Panel who has since been absorbed by Leonardo. It works just like other backlit aircraft panels. Small bulbs (likely incandescent) within the frame illuminate the entire back panel. The opaque top layer is etched away at specific areas to illuminate text and control positions. This panel's backlight uses 5V DC as indicated by the markings near the connector.

Here is the front of the panel with the backlit section removed. This panel features a nice blend of Korry-style switches and indicators along with traditional toggle switches. The circular connector in the bottom left corner is for the backlight connection.

We removed the rear plate from the standoffs and removed the connector from the plate to trace out the wiring. We ended up cutting off the large twist-lock connector as purchasing the mating plug would be quite expensive. When we integrate this panel into something in the future, we will probably use something more common such as a DB-25 connector.

Below is a picture of the panel with only the backlight illumination powered on.

The image below represents the actual color of the backlighting better than the previous. It also shows the Korry indicator lamps powered up. Some are brighter than others, but they all use 24V DC, unlike the backlight.
