I need some information on a large format lense (uncoated). The following info is printed on the lens:

Schneider Kreuznach Doppel-Anastigmat Symmar f=6,8 F=30 cm (mounted in Compound-shutter)



First, is it a dagor-type lens ?

... is it a convertible lens?

... covers the lens 8x10" with movements?

... is there anyone, who works with such a lens?

Thank you in advance, Ronald.
