Hello all. I recently bought some merchandise from a long time rc pilot that recently passed away. On of the things I received is this glow plug. Can anyone identify this? I know the center post on glow plugs can be unique. Now, I wouldn't be asking this for just one plug, I would just throw it away, but I received about 38 of these and would like to know what I'm dealing with. Any help would be appreciated. Thanks oh, also, there arent any markings on the plugs
