The Printex camera (from 1946) was (the only model) made by Printex Products of Pasadena (CA.) in both
4x5" and 2 1/4" x 3 1/4" sizes. Uses an unusual telescoping lens mount (versus bellows),
as can be seen in the photos above.
This is a rigid body all metal press camera similar in function to Speed Graphics etc.
While not common, the camera rarely fetches more than $100 to $150.
