New uniform buttons:
South Australian. Melbourne and Metropolitan Tramways board existed between 1919 and 1983.
The AMF button is a puzzle. The company changed its name to K.C. Luke (A/Asia) Ltd in May 1953, and yet the button features a “Kings Crown”. As King George VI died on the 6th February 1952, this crown should not have been used! I wonder if the button was made in 1953 but not issued.
It is not clear from the photo, but some ‘Staybrite” buttons in the gold tone made by Stokes seem to have faded. I have a few buttons with the coating look faded and chipped. Perhaps they had a quality control issue, or they did not wash well?
