Extra Characteristics In Some Whistles 

Flaws or Deterioration in Address stamps can help you to date Whistles in a glance.

 1901 Whistle

  The 1901 whistle is the only whistle with the 1889 - 1901 address stamp that has the CURVED J.Hudson&Co with a thicker concave loop.

   Sometimes its hard to determine if the loop on the 1901 whistle is either the thinner pre 1901 or the thicker 1901 - 1908. To determine if you have a 1901 whistle you can also look at the top left part of the 'B' in Birmingham to see if its missing.

1908 Whistle

1907 - 1913
