SOM Berthiot reflex 17-85

[Klintan]

Hi everybody,
my first post:
I need to change the angle of the viewfinder on the camera. It shall point 45 degree up to the left, but than it is not fully seated on the c-mount thread. There are three screws on the barrel that looks as if they could be setscrews, but who knows!
Does somebody here know?
cheers
Hans

I assume this is for mounting on an H16? It’s been a long time since I used one, bur I do recall being perplexed about getting the viewer properly placed while having the lens properly lined up with the C mount. Bad news is that I don’t remember the proper adjustment. Good news is is that I’m pretty sure I didn’t have to unscrew three set screws. Sorry this isn’t very helpful.
