Recognise a curious device?
Does anyone recognise this? Or have any idea what the modes might mean (T/A, T/G, ...)?
It might be from the mid 1970s, perhaps from a military aircraft.
Details of the interior are at Inside a vintage aerospace navigation computer of uncertain purpose.

In the context of a vintage flight computer, "T/A" typically stands for "Time/Altitude" and "T/G" stands for "Time/Groundspeed".
- Time/Altitude (T/A): This setting allows pilots to calculate the time it will take to reach a certain altitude or the altitude to which they will climb within a certain time frame. It's useful for planning climbs or descents based on time constraints or for determining the altitude at a specific point in time during a flight.
- Time/Groundspeed (T/G): This setting is used to calculate the time it will take to reach a certain point on the ground based on the aircraft's groundspeed. It helps pilots estimate arrival times at waypoints or destinations by taking into account the speed at which the aircraft is moving over the ground.
It seems low accuracy for navigation in the 1970s, .1 of a degree, plotting to the nearest point corner within roughly a six mile box, add to that the INS errors over distance.
