Specifically, the file Philco Speakers - speakers.zip.
Now:
Both are 10-1/2 inch speakers.
H13 - 1125 ohm field @ 65 mA; output transformer primary 5,900 ohms push-pull to match 1.25 ohm voice coil
H16 - 660 ohm field @ 80 mA; output transformer primary 7,200 ohm single-ended to match 1.25 ohm voice coil
If you were to use an H16, you would need to add resistance in series with the field or else your B+ would run too high. Plus you would have to replace the output transformer with a suitable push-pull unit.
