One of the best triplets and maybe more fun than the Tessar. I have a 6x9 Patent Etui with a Meyer, but a Helioplan.

DRP just stands for Deutsches Reichs-Patent, so they were probably made by a third party manufacturer.

What lens does your Patent Etui have? I'm a hoarder myself and made a shelf in a wardrobe break because of all the photo equipment. 😄 I found a roll film holder that fit the 9x12 Avus in the pile of stuff.

You are probably right and have better source materials than I do (speculations on Camera-Wiki like "It is quite possible that production (of the Gitzo Vario clone) started during the war when German patents were in abeyance. Certainly after Germany's unconditional surrender in 1918 French...

That's not the Alfred Gauthier Calmbach AGC logo, but the Arsène Gitzhoven AG logo.

I've been wanting a remote control mechanical shutter release for many years, so I might buy one of these. I already have an extension that I use with the Autoknips IV selftimer on old dial-set Compur shutters.

The shape of the release lever looks more like the Gitzo: The Gauthier Vario for comparison:

"Novar" was a name they used on lenses from different manufacturers. Most were triplets. The 6,8 would have been a little cheaper. Sorry to hear about the theft. 🙁

It might have been sold by a photographic store or mail order company under their own name. "PARIS" is a strong clue. The lens is French, and the shutter is most probably a French GITZO Type B (Pretty much a clone of the German Gauthier "Vario" shutter). Gitzo was founded in 1917, so the camera...

That is my guess. I might be wrong, so contact https://zeissikonveb.de and see if they know more. The later "Jena" and "Aus Jena" lenses, marked so for legal reasons were marked "DDR" and had the East German quality mark (an 1 inside a Q). And the normal production of post war Carl Zeiss Jena...

The "C. Z. Jena" and red rhombus instead of "T" are most probably done like that for legal reasons, and note that it says "Germany" instead of "DDR" or "GDR", so I think it was made before East Germany was founded. Maybe https://zeissikonveb.de has the answer?

I found this on eBay, and there is the paper that came with the Walz filters. It's indeed a normal yellow-green filter. https://www.ebay.com/itm/383937163597 The hue of the yellow-green filters from different manufacturers vary a little but the effect is the same to human eyes. The colour...

You still need to fix the film!

Yes, the Voigtländer one will work.

That lens kept the original Heliar layout, and the test images I've seen show some of the Heliar character with the "almost 3D" rendering, which I liked. The original Heliar from yore wasn't known to be the sharpest of lenses, but then we are talking large and medium format versions. Cosina...
