It does look unfinished. A bit of a story to go with this. I have, in my collection, a series of Cooey model 84 receivers, 5 in total. They are in various stages of completion showing the steps they went through on the assembly line, from rough foundry cast to finished product. They came from the fellow who wrote the Cooey book. I doubt very much there is another set out there. Now if one didn't know the story or history behind them, one would wonder how these came about so many years later. Possibly the same type of thing with this Martini action? Possibly a defect was noted along the manufacturing process so it was set aside only to be swept up by an employee of the time? Another "new" mystery.
