For some time an old rusty lens/shutter has been collecting dust on my shelf. I took it down today to give it a closer look, and perhaps it is more interesting than I thought.
The lens is marked as "EURYPLAN-ANASTIGMAT SERIES I F:4,5 FOCUS 8 1/4 INCH" in a yellowish writing, and then "A. E. Staley & Co London E. C " in a different font with white letters. There is a No. 2047 number on the outside of the front rim, and the same number on the rim of the rear cell. The lens is symmetrical, front and rear cells giving 5 reflections each, out of which one is weak. The front cell is possible to unscrew, an I can loosen a cemented doublet, and the front element then stays in place. The complete lens seems to be a 1-2-:-2-1 configuration. Is this a Plasmat, even if many of them ( such as symmars) have the doublets longest away from the aperture? The Planars had 6 single element, I think...
Was Staley a manufacturer, or just a company that stamped their name on products they sold? I found in another thread that they around 1900 sold the Swiss Suter lenses.
Does the name Euryplan indicate that this is a construction with wide coverage? For the time being I really can't say, because the old Compound shutter is stuck in closed position...
