I also don't know why sometimes in German the first name is rendered as "Carl" and other times as "Karl". Maybe someone out there can tell us.
No, the Meyer company was reconstructed a couple of times, changing hands and names. If I remember correctly, the name Meyer was dropped for a while when the company was integrated into Pentacon back when it was owned by the East German state.Meyer Optik
Meyer Gorlitz
Are these also subtle variations to get around a patent?
Maybe they simply told the engraver to "use the made up name Carl Meyer/Karl Mayer for that batch", and the engraver spelled it as he or she heard it.
My great grandfather spelled his name "Carl", but it's spelled "Karl" in the censuses and official papers. Carl is also one of the names that got "translated" into other languages centuries ago. Carl, Carolus, Karel, Charles, Carlos, Kaarle. The names of old Swedish kings who spelled it with "C" have now been standardised to be spelled with a "K".
Names beginning with an "I" sometimes used a "J" instead, and vice versa. Agfa Jsolette/Isolette. Jgestar/Igestar.
IVLIVS = Julius in a very old spelling.
Names beginning with an "I" sometimes used a "J" instead, and vice versa.
In old German fonts I (eeh) resembled J, while J (yot) had a horizontal stroke that distinguished it from I. So it has always been Ihagee, Icarette and Igestar, but they were rendered differently in the older fonts. Of course, this does not solve the mystery of Karl vs. Carl and Meyer vs. Mayer.
Interestingly, Carl Paul Goerz spelled his name like this (Carl with C and 'oe' instead of umlaut).
Or maybe someome thought that it was too obvious that "Carl Meyer" was "stolen" from Carl Zeiss and Hugo Meyer...Thank you for the picture. I caught the "Karl" with a "K" in your post but missed the "Mayer" with an "a" (vs. "Meyer" with two "e's"). Maybe as JPD suggests, who ever was operating the pantograph engraver at B&J that day turned out a bunch of Karl Mayer instead of Carl Meyer lenses...

It would be interesting to know if "Carl Meyer" was a registered trademark by Burke & James. The spelling would have been important if it was. If not, then "Carl Meyer" was nothing more than an ornament, free to use. Unless someone else trademarked it and was in a similar business, and B&J had to change the spelling because of that.
Thank you for the clarification. Josef Schneider and ISCO did puzzle me.But it's also correct to spell these names with an "I". Beginning an "I" name with a "J" is still done sometimes.
Thank you, then the spelling is important. Textile equipment has probably nothing to do with this weave of mysteries.That's easy to find out: search at https://tmsearch.uspto.gov/search/search-information

Burke & James applied for the trademark related to photographic lenses in 1960, registered in 1962, but the application says first use 1932 (perhaps a re-registration?). It expired 1987. Also, "Carl Meyer is a fictitious name."
Searching for "Karl Mayer" reveals that there is a German manufacturer of weaving and textile machinery, which still exists. B&J doesn't seem to have had a trademark on "Karl Mayer."
From what I can see this looks like an Alphax shutter, US made by Wollensak.What is the shutter called? That could give us a hint if it is west German or GDR. If it is German at all, that is.
OK. I can't find published data for the lens. No angle of view, etc. Trigonometry is out. I can mount the thing in my front standard and essentially remove the rest of the camera. Would this help me figure out coverage? I've read that looking through the clipped corners only gets one a rough idea.
Get lens mounted 12" away from a wall (12" focal length), shine a light through it, measure the circle? Is that a valid methodology?
