Between the No.0 Windsor (1915 general catalog) and the No.210 Supreme (1917 Supreme catalog) there was the No.0 Supreme and the No.210 Windsor. The 0 Defiance is a 30's thowback using acquired Defiance tooling. The No.10 Supreme appears in the 1920's as either a supplement or a replacement of the 210, using the same Embury details. After 1930 the No.10 Supreme also becomes a throwback with Defiance tooling including the 0 Perfect lift plate and the match-striker tube. Embury went thru so many name and number changes and gyrations that one truly needs a program to tell the players. BB
