Probably an Oxley Thermotrimmer.
If I remember right, the Tempatrimmer was a differential capacitor adjusting the proportions of a pair of fixed capacitors, one negative tempco, one positive, while the cheaper thermotrimmer used a bimetallic strip to move split 'stationary' plates that the rotor plates got a variable tempco. Could be somewhat vibration sensitive!
