Paillard Bolex H16, need some help

[Markus Ottosson]

Hi

I bought a Paillard Bolex H16 a while ago that does not look quite like any other, seems like someone has modified some extra accessory to it.

 

Here are som pictures

 

A closer look

The darker part of the "disk" is magnetic.

 

And this is connected the "thing"

 

I've also uploaded a video so you can see how it works

Anybody have a clue?

I'm new to these kind of cameras so I have no idea.

The magnet likely acts on a reed switch which will close once every 8 frames.

It might be to control an external digital frame counter but it wouldn't be very accurate.

At a guess it's a home-made tachometer, probably used to set the speed as accurately as possible. With each revolution of the disc (8 frames) the magnet will trigger a switch to create a pulse, so exactly 2 pulses per second is 16 fps, 3 pulses per second and you're at 24 fps. Presumably there was a readout box that the plug fitted into.
