8x10 Bauch & Lomb Protar from 1891?

[Peter Hughes]

A friend of mine lent me an interesting old lens, dated '91 (1891!) an 8x10 Bauc h & Lomb Protar. The f/stops go from f/18 to f/90. It seems to have a focal leng th of about 5 or 6 inches, but no focal length is marked anywhere on the lens. I t covers 8x10, very wide angle, as you might expect. No shutter, barrel only. Do es anyone know anything more about this cool old lens? I'm using on my Deardorff 8x10 with great results.
