The Hemsley-made buttons for the CAF (circa 1920) are quite rare. In an earlier post I reported on a mid-size CAF button made by Hemsley. That thread is perhaps incorrectly located in British Military; Military Buttons:

I’ve recently discovered another manufactured by Hemsley, this one is the smallest size, for the Field Service (Side or Wedge) cap. It is observed that the Hemsley-made variant is slightly larger and heavier than the more "commonly" found Field cap buttons. The Hemsley illustrated below weights about 2.45 g and is 0.051” (13 mm) in diameter. My other small-sized, Field cap buttons, including the 1967 reproductions, measure about 0.45” or 11.5mm. The others, assumed to be manufactured by Scully, are all unmarked on the back, probably due to space limitations. Most weigh 2.3 g, including the 1967 replica. The quality of the strike is thus probably the best way to distinguish the originals from the '67 reproductions.
I have yet to come across a full sized CAF uniform button made by Hemsley but if anyone has a spare, I would be interested in acquiring it or at least knowing that they in fact exist.
