I’d like to build a single blade shutter into my B&H TQ3 16mm projector.
It now has a dual blade shutter, but I'd like to obtain more flicker, and possibly more light.

Does anyone have any idea where to find these kind of shutters?
Ideally, these would be for sale somewhere.
Or which older model projector would have a compatible single blade shutter?
If this is impossible, the shutter needs to be custom manufactured.
Would this be as simple as cutting one blade off my dual blade shutter? Or does this yield to unwanted effects?
Are there any standard single blade shutter designs around? Calculations for the counter weight?
Years ago I removed the shutter of an Eiki projector for special effects with external shutters, but for sync and portability, I’d like the shutter of my B&H projector inside.
Did anyone here switched shutters in 16mm projectors?
Ideally, as the shutter is in the middle of the projector, someone in Europe who's experienced with putting back together and finetuning wants to do this for me.
Any links to or info about single blade shutter designs, shapes and sizes is very welcome.

I'm currently reading "A STUDY OF FLICKER IN 16-MM PICTURE PROJECTION" (around page 232)

A warning.
Flicker can cause photosensitive migraine in some viewers.
