I am a new member. I work for a NH firearms auction house, and sometimes I find items that are too esoteric for anybody here to identify. I often buy them for myself or to sell or give to others. Today, we got a weird pistol grip electrical switch with Japanese markings and a Naval anchor mark. It is about 7" long, and has a "barrel" about 30mm in diameter.
The trigger mechanism pushes a rod inside the barrel that makes an electrical contact. The contact has the remains of an electrical cord that obviously came out of the front end to operate a device.
There is a bail at the top for hanging the device. There is a flange at the front where the cord came out for inserting this into something else and locking it with a set screw.
My best guess is that it is the trigger for a signal lamp, but it could be an actuator for an electrically-fired weapon, too.
My questions are: What is this? What is it worth? If it turns out to be something I don't want for my collection, is there anybody who wants it if I buy it at the auction in May?
