Silver Whistles

Here I have four silver whistles marked J.Hudson Co. First is a 1905 round whistle, Second is a 1902 escargot whistle with PATENT on the side, Third is a 1913 silver flat Whistle and Fourth is a modern Acme DOG whistle (just like the plastic Acme Field Trialler no 212) , stamped ACME under the window, ENGLAND #212 on the back.
