Can anybody please identify the application (aircraft type) for one, or both, of these Desynn Position Indicators. (Asking for friend WV-903)

Hi Terry
This particular design/shape of indicators/gauge(s) seemed quite fashionable in the early post war years.
Trouble is there are lots of variations/application of indicators/gauges and they will all have different part numbers although they are identical in layout (but for different applications of course).
For Naval a/c – the Attacker definitely had a similar Flap ? Desynn Indicator on the port instrument panel just about where one might find a flap indicator + a Trim Indicator ? just aft of throttle + perhaps another just fwd of throttle/trim wheel.

Swift VV119 appears to have 3 x gauges of similar design

Many thanks Dave. Now I hope someone might find pictures of them in situ, I shall be checking all my naval aircraft images.

Hello Terry,
In AP1086 Sec 6A dated Sep 1966 452FL is listed for Naval Aviation Only without type with Sec/ref of 6A/3349
6A/3731 is a Sangamo Weston oil pressure gauge 0-120 psi, but 426FL is listed under part number and equates to Sec/ref 6A/3781 again no type but for Naval Aviation Only with description of Indicator, Position, Desynn Type Aileron and Rudder fluorescent
Oddly I have 426FL listed in Smiths maintenance manual 31-09-50/2 as Oil Cooler indicator
Regards
Dave
