The movement is an adaptation of the Williamson movement of 1908. What makes this camera stand out is the shutter fade mechanism. It is its own unique gearing that I believe allowed the Sterling Camera and Film Company to apply for a patent.

 

The accessories and case are a wonder to hold. This is the most "museum piece" camera because it has so many of the original factory accessories and the magazine case. The camera comes with an unheard of six magazines. The frame punch is the most unique I have ever seen. The single frame crank is here too. The many mattes include binoculars and one I have never seen before, cloverleaf.
