Submitted for your approval is this Circa 1942 Weston Photographic Analyzer. The set is in a wonderful state with the factory original metal baked paint and Bakelite case.
This item was used to measure the density of a photo negative and is called a Densitometer. This is a very clean example, beautifully preserved and unrestored. Offered for display on a desk, bookshelf, library table or in a collection.
Makes a great library, trophy room, office display or collection piece. A true photographic measurement artifact.
