Lots of tarnish on the outside, but the glass is like perfecto. This one is also featured in Dan's wonderful 1890 Benjamin French & Co. Catalogue. It's actually about 160mm focus f4 according to my measurements. I didn't do any photos with it. It should just cover 4X5 even at infinity I think. This was probably originally one of 4 identical lenses that made 4 carte-de-visite images on the full plate. Today it will make one spectacular image on your 4X5 Apertures are for sissy's. There is none. Solves hours of dilemma's worrying about which aperture to choose. Brilliant. $225 + shipping.
