Reflex viewing with non-reflex Bolex

With the older Bolex H16 non-reflex models, I do know that there is some way to accomplish temporary reflex viewing before exposing film.
Hm, I have a reflex model, don't know to much about the non-reflex models, but I never heard about such a thing. There are Pan Cinor lenses with dogleg viewfinder,
and there is the viewfinder on the side of the bolex that needs paralax correction and can't be used for focusing...

I've seen these show up once in a while on eBay though you might ask dealers like Chambless if they have one.

Often on non-reflex bolexes there is a eyecup on the top of the camera at the front above the top turret mount. If you turn the lens from the taking position to the top position on the turret you can look through this eyecup for through the lens focussing.

There is a Bolex rackover made for non-reflex H models. ...
Besides this, Bolex used to make devices that fit into the film gate after removing the pressure plate. Basically a groundglass, mirror and magnifier. These would be useful for the initial setup of something like an animation stand, and very awkward and impractical for general filming as there would have to not be any film in the camera when using it.
I believe they made two styles, for below serial 100400 with the cam-driven claw, and above serial 100401 with the so-called registration claw. The wrong one will not fit. In my senile state I don't recall what they were called.

Bought myself an H-16 couple of days ago,
going to restore it to best condition. Now my discovery, perhaps nothing new to some of us, but nevertheless: I have never tried to put an H-16 with big base on the rackover (models sold after 1963) until today because I thought that were not possible. Brain is not everything,
it is perfectly possible!
Now we also know why there are three tapped holes in the big base. The rear one is used when camera is put on rackover, the front one usually chosen for camera together with the weight of three lenses. I have a couple of big-base Paillard-Bolex H cameras.
Rackover work most often is one-lens work at very close or macro distances. It’s also mostly about compact and lightweight lenses, possibly even symmetric designs around 1:1 ratio.
I strongly advise against the use of the film-gate prisms. Glass is harder even than hardened steel and when moving the ground prism surface over the polished film rails one risks to scratch them. Gelatine will likely find a halt to sit down and build up in scratches. We don’t want that. The rackover allows to keep film in the camera, the gate prisms don’t. The Paillard-Bolex rackover links us directly with the Bell & Howell Standard camera of 1912. Bell & Howell offered a similarly reduced three-port turret camera, the Filmo Viceroy Double-Eight, and a horizontal rackover device to it. Extension tubes complete the system for stunning macro shots.
