Closer to a Tessar, I think, but really not quite either one. A very nice bright lens either way. I have a coated one, although I see uncoated ones from time to time. Mine has no aperture, but apertures are for sissies anyways!

It is definitely closer to a Tessar. It seems the second element from the left of Zeiss Tessar diagram is split in two. I am impressed by its sharpness, definitely better than Pentac lens wide open. And yes, there are coated and uncoated versions. I have both.

Do you have one of these lenses? 135/3.5 Aero-Ektars are uncommon. I've never seen one, despite working for 25 years in the Kodak building where they were made. The other 135/3.5 Ektar that Kodak made was in a mount for the Hasselblad 1000F/1600F. Those are quite rare and I recall donating a battered one from my department's 'junk box' to the George Eastman Museum.
135/3.5 Aero-Ektar? Is there such a thing?
The OP has a 13.5"/3.5er. They're not that rare. There's currently one on offer on eBay and another has sold within the last 90 days.
Oops, my bad. I should read the fine print before I write.
