Someone could help me with this lens. Cover 8x10?. Fine for Portraits??
I had never seen one with waterstops...

Way more than adequate coverage. I was happy enough with my 14" on 8x10. And the coverage will increase at portrait distances. Is it coated? It doesn't really look like it, but hard to know from pictures. Some were, but most pre "red dot" were not coated. 8 air/glass surfaces so the possibility of high flare. I did have an uncoated 19" and don't recall any problems, but that is a lens design where I'd prefer to have coating.
It will be fine for portraits if you like them sharp. F9.5 is going to be a little dim for focusing portraits in normal indoor light levels, but not hopeless. I can think of a lot of lenses I'd rather have for portraits, but they will tend to be more money.
Waterhouse type stops I believe were to allow different aperture shapes for printing industry needs. Does it have an adjustable iris too?

Per P-H Pont's Goerz chronology, the lens was made between 1915 and 1920, very possibly before 1918. Uncoated from the factory, coating hadn't been invented yet.
Wow! Looking at it I would never have dreamed it was anything like that old. I thought my 1928 42cm Apochromatic Claron was old. That was my main lens on #10 Cirkut for decades. Coated at some point before I got it.
Thanks Mark,
It has no iris and as Dan says itīs not coated. Only the slot for waterstops.
I read somewhere that they were made with iris and a slot that allowed to use filters in graphic arts work, but this only has the slot for aperture waterstops. I've never seen one like this ...

Total ignorance. I've never had an Artar.
I have and have used dialyte type Apo-Nikkors and Apo-Ronars, always at distance. I like what they do but I'm a certified ignorant barbarian insensitive to the fine points (took the course, passed the exam, have the certificate) so can say nothing about bokum.
You have the lens, ask it.
Artars are quite desirable IMHO. I have 14"& 19" Artars and am very satisfied with them both, but what Dan Fromm said---it's your lens!
