Seems that the interlace filter design was not exclusive to Pye. The Pilot CV34 from 1950 employs a similar circuit. The frame and line sync pulses are supplied to the cathodes of the Mazda T41 thyratron oscillators. It's an unusual arrangement but it works. Some time ago in an attempt to improve the interlace in a Dynatron "Fulmar" I modified the set to incorporate the Pilot frame sync and oscillator circuit. In the Fulmar the the frame oscillator thyratron is a Mazda 6K25.
