Bausch Lomb Zeiss Convertible Anastigmat  14" & 19 1/4" Large Format Brass Lens. Serial # 56131. Glass is surprisingly clear with minimal haze, some faint scratches and scuffing but overall very usable. There are traces of balsam separation at the very edges but very little and only at the extreme perimeter of the lens. 

This is in a Bausch & Lomb Shutter and has not been tested - it is designed to work with a rubber bulb and hose to trip the shutter. Things appear 'stiff'.

A convertible lens like this is actually 2 lenses in one depending whether you use the front lens cell, rear lens cell or both. 

Going to sell as is since the lens truly cannot be tested without the correct supplies.

Again, coming from the lifetime estate collection of my father. Thanks. Local pickup is available 21128.
