Refering to the first paper:
Looked like the 2 major german manufacturer for camera equipment almost unificated in a time when their whole Super8 imperium was threatend to be overun by the video tribes.
'You know what this "core drive" technique of that Bauer S 307 was? May be good against jamming cartridges, eh ?
As far as I know (or remember) Robert Bosch GmbH owned Braun that in turn bought Bauer or vice versa of the latter two in the end. Somehow unified yes. Bosch seemed put them together in their "Photokino" division, Cameras, projectors, flashes and you name it.
Actually a friend of mine worked as a sales Agent at Bosch about the time I got these booklets, about 1985/86 and when he saw my S8 cam he announced proudly that he sold the Bauer Video cams! and!! could not differ the S8cam from a Vcam!!!
If you take a look at the brochures you will see that there are printed Robert Bosch GmbH at the last page.
Also have a contemporary brochure for the projectors that I will post later.
Sorry but I do not know the details of the "Core Drive" but it is obviously designed to stabilize the filmstransport all the way. By explanation pretty good.
A friend of mine owns a S307Xl so if he still has the manual I willl try to look into it to see if there are more info available.
From my experience with the "jerky carts" I will not recommend to use them if they block. The load on the camera seem to be tremendous and I would avoid it.
Bauer is the camera/projector brand of the Bosch company since generations. Nizo had been together with Braun, and Agfa cameras look like Nizo. If Bosch and Nizo also had married short before they died, I don´t know...

Sure you know more about this than I do but at the time of this last? S8 brochures were printed it was Bosch´s Photokino division (flashes and everything about Photo and S8 film editing/sound ++++) bagged Bauer/Braun/Nizo all together in these booklets.
Ref rear side of the Projector booklet to be posted:
So it seems, that all German producers had joined together in the end. I have only post-time knowledge, as back in the 1970ies and beginning 1980ies, where new cameras still had been availabe, I was a college boy and had no budget at all! I only could afford S8 cams and basicly the expensive film stock, in the end of the 1980ies and later.
