CHOROSKOP II Brass Wide angle Meniscus Lens ?

Hi, just found this little Meniscus lens.
Can someone tell me the coverage ? Any infos ?

Found only one info on the web.
Scovill 5x7 camera with a similar lens.

Does anyone know if this could cover 8x10?

Thanks
J

I have seen a couple of these tiny landscape lenses with built in shutters. I still have one!
Landcaster made a detachable type as well.
If the spring breaks, you always use a rubber band to create the right degree of tension!
The engraved "lightning" schematic suggests the Lightning Brand, which was a name given to some imports into the USA from France (A.Laverne, perhaps?).

Goerz Choroskop No. 2 - Periscopic type lens

Steven - this is your scan !

Yes I know!
I assumed it was a counterfeit use of the tradename as I couldn't believe that Goerz wouldn't have had their name somewhere on the lens and made the nasty trademark line!

HOWEVER, looking at the catalogue again, I can see that this landscape lens was sold (at a very low price!) complete with a wheel stop and a shutter (of sorts).
To make amends, I have included the very poor engraving of the model from the same catalogue as the table above. You can just see the special C loop.

This is a very rare lens - I have never seen one. Quite a few were made, but if they don't have the Goerz identification, it could explain why they have been thrown away.
Covers only 5x7 at small stops.

Thank you for the info.
So I will try it on my 4x5 Cham.

Any info on the value ?

It is very uncommon, but unless there are at least 2 goerz collectors who want every model that CP Goerz ever made, it would have the same value as the very common small Lancaster meniscii. I have sold around 5 of these during the past six months in the F/S section for small amounts. Meniscus lenses are fun.

This was one sold for 120 Euro

I have one of these sans the shutter. Never used it yet, maybe in the spring..
