Some of Carol’s recent finds:
Victorian Artillery button with Lincoln Stuart bachmark:
AMF button with ‘Commonwealth’ backmark:
If this refers to the clothing line of Foy & Gibson, it may be that they supplied uniforms. An alternative is that the button was on a uniform made at the Commonwealth Factory located in Melbourne. However, I don’t know who the button manufacturer was.
This design is seen on Beauclaire cards from the 1950s. Could the capital H stand for Herrman?
Berthold Herrman founded the button manufacturing business that became O. C. Rheuben, then General Plastics (the makers of Beauclaire buttons).
