Edwin L. Oswald Collection
This is two guys getting ready to fine-tune the twin 50s on a Mark II. I want you to look very carefully at the rear part of each of those guns, and you'll see, standing up, a silver-colored box about the size of a cigarette pack. Those are solenoids, and they can be goosed up and down to either make the guns fire faster or fire slower. We carried 300 rounds per gun on a patrol and depending on the situation, we could either pour a lot of lead in a hurry or if we were low on ammo and wanted to save it, using those solenoids, we could tune the guns downward so that they fired even slower. And again, notice the lip around there, the gunnel. See the little yellow light there in the lower right. That yellow light sits below the gunnel. Keep your eyes open for this when you see it.
