That's quite an impressive array you have on display there Philip!
The only one of that assortment that I possess is the Bosun's Whistle, only mine is not plated as is yours, but is simply showing raw copper and brass with a bit of exposed solder. It is however, clearly marked "THE ACME" in an arc, under which is smaller letters "Made in England", all on one side of the keel, so I assume that qualifies?!?!
