Wollensak 15 Inch f/5.6 Telephoto for 4x5 GOOD-

Glass looks good with a few dust motes inside. It is moiunted in a Alphax shutter with speeds from 1/2" to 1/50th", B and T.  Speeds sound accurate.

The lens is somewhat crudely mounted in a 4x4" wood lens board. It appears silicon sealant was used to attach the lens.

Comes witrh an adapter thast asllows you to use 77mm filters. A Nikon 77mm UV is included.
