Information about Zeiss Triplet WWI

[andrehh]

Hi,

I'm looking for information such as coverage of very old Zeiss Triplets made at the time of WWI.

The VM is mentioning them, but not showing details as coverage or angle. The fantastic list of Arne Croll is starting with Zeiss lenses made in Jena 1950 only, but I´m looking for older lenses.

Any hint for infomation is welcome.

Which triplet?

I´m interested in the "big ones" 50cm, 70cm and 120cm focal length.
