Capt. - thanks for sharing that is a cool photo!! Showed this photo to my father - who was Korea era enlisted, vietnam era officer in Navy.
While photo is before his time, he relayed that this looks like a typical picture of either a base patrol muster or pier master muster with security personnel present - that he has seen elsewhere from same time frame. He also mentioned that the amount of equipment needed to outfit Navy bases in the 40's especially in the Pacific starined available resources and anything that still worked, old trucks, weapons, aircraft, etc... was used
Heck while I was on ships in early 90's our preferred line throwing gun was still a 1903 springfield converted a bit for its new mission, the M-16 version did not have enough "umph" for anything other than training in good weather only.
When you had to get that tow line over or mooring lines in bad weather and wind - that ole springfield never failed my guys. I even had to use it once due to the sensitivities of people parking their cars where they shouldn't have.
I didn't mean to - but i busted the heck out of someones window in their new truck that day - the admin staffer from the base, parked in a clearly marked no parking area, was not pleased but my skipper met him on the brow and took care of it.
