Over the years that film and the H16 camera system was king Bolex produced all manner of weird and wonderful accessories for its cameras.
The majority of which can be fitted to mostly all H16 cameras from the start of production up to the SBM as they all have the same profile.
The EBM and EL having a different profile and needing their own specific accessories. Some nowadays are obviously more desirable than others.
Cases, Handgrips, Cable releases and Tripods are always handy to have. Anamorphic lenses and a 3D filmaking accessory called the Bolex Stereo are more a curiosity now than being very practical.
