US Patent number 528155; patent dated October 30, 1894. I have included a photo of the signed patent certificate and the interesting scientific details provided by Goerz regarding the optics, which I have linked to here. Goerz was known for his pioneering work and producing very high quality lenses. 1 5/8 tall with cap.
The non-matching Leitz case is 2 1/2" tall and 2 2/8" diameter. I examined both lenses with a loupe- there perhaps is some haze or could use cleaning.
Please review all of the photos as they are part of the description. _gsrx_vers_1652 GS 9.7.4 (1652).
