You want a 6 inch electrodynamic Philco speaker with 1100 ohm field coil. This eliminates the 41-221 as a possibility, as its speaker is smaller than that.
The original part number is either 36-1483-2 or 36-1483-4, used in models 40-150, 40-155, 41-250 & 41-255.
Similar models with the same field coil specs: 36-1519-3, used in model 41-256 & 42-355.
Models 39-25 and 39-30 also use 6 inch speakers, but their field coils are rated at 2000 ohms.
Enough 40-150, 40-155, 41-250, and 41-255 models were made that you should not have too much trouble finding a suitable replacement.
