The non-linear calibration of the gauge (does it actually say "FILM GAUGE"?) fits with film being wound on a drum, so the nearer to the middle the shorter the length of film rolled out per turn of the drum. Other parts could easily be shutter releases, etc., but equally easily they could have some other purpose.

I acquired a few early aircraft gauges etc recently, & amongst them were these interesting bits.
The gauge is made by Williamson of London, whilst the control mechanism is made by Ross Courtney.
If they are for aircraft use, I would guess their age as about late 1920's or early 30's.
Any ideas ?.
