THORNTON PICKARD ANTIQUE SHUTTER.
Beautiful antique front mount roller blind shutter.
Works well on the speed it is set at. I have not tried to change any settings.

Mounted on an about 3 1/8" X 3 1/8" lens board which can be easily removed.
Has lens adapter wood board on front with 2" opening. This is removed by turning 2 "L" screws.

Very collectible and useable.

May be returned if not as described.
