Hard to find Vivitar PG-1 Quick Release Pistol Grip that connects with the CB-35 35mm Bracket (also available here: Vivitar CB-35 camera bracket). Idea for use with any hot shoe flash gun including the legendary Vivitar 283. In good condition.
You don't have to use it with the bracket. It makes a brilliant grip to hold a flash with modifier from a height, when doing strobist work.
