I have three teeny-tiny brass wide angle lenses that are marked as being for 8x10. These are barrel lenses, no shutter. Never had shutter. Would anyone think these might take decent b/w photos? Two of them have stop wheels you turn to set aperture stop, various size holes on a rotating disc. The final one has a conventional iris diaphram. There are two almost identical lenses. One says: J. C. Somerville St. Louis Mo 3726 8x10 No. 2 this one has a stop wheel with stops from 16 to 512 Another almost identical one says: Schiller Extreme Wide Angle Anastigmat 8x10 this one has a stop wheel with stops from 16 to 256 And a larger one with iris diaphram..still brass though: Seneca Camera Mfg. Co. Extreme Wide Angle 8x10 The iris is from 16 to 256 Any advice or information on these would be appreciated.
