Floyd99,
You have a third model Worcester Pressed Steel, “Standard New York Drum”. You are correct that this drum is after the numbered drums and the Stanley, “No_______”, Un-numbered drums. The drum has the nickel colored rotor and looks to be in good shape. I would estimate the value anywhere from $1,500.00 to $2,000.00. You might get more than $2,000.00. Estimates are subjective. These drums were made in the 1928-1929 era up until 1931 or 1932. The next Worcester drums had similar markings but had blued rotors.
