In regard to the ice cream machines.
I've heard many stories about how US Boats "acquired" ice cream machines, even though they were not standard issue.
While it may not have been standard practice, it was not unusual, for a sub crew to steal a machine, if the opportunity arose.
Perhaps, the US and Royal Navies', high command, opinion, that Submariners were half brother to pirates, was closer to truth, than insult.
One storey, of note, was told to me by a guy who was on a brand new Gato, in early 42, out of Pearl.
They were tied up near a Carrier, under going extensive repairs (Yorktown before Midway?).
A chief, on board, put together a volunteer, working party, and paperwork, and headed to the Carrier.
They approached the Carrier's Supply Officer and had him sign off on the work order (talk about "stones"!!). They, then, proceeded to the mess deck, where they removed the machine, transported it back to the boat and installed it.
Nothing was ever heard about it, and it was still aboard when my friend left. the boat.
Perhaps, the loss of Yorktown, at Midway, saved their butts. We'll probably never know, since my buddy died several years ago, and he never said, and I never asked, which Carrier it was.
With the datails he gave, if he wasn't the Chief, he was part of the "working party.
