Iver Johnson Prototype .25ACP Blow Forward Pocket Pistol

This is a one-of-a-kind prototype of a .25ACP blow forward pistol made by Iver Johnson. It was patented in 1916 (patent applied for in 1912) by William O. Barnes of Massachusetts, and assigned to Iver Johnson. We don’t know much more about it, but it was probably dropped by the company for not working well.
