1928 victor talking machine radio acquired

I recently acquired this non working radio. In fair shape but an open in the center tap of a 5v filament winding (I can work around this) . Also, the electrodynamic speaker field coil is open (corrosion on one end) I have a Ryder circuit diagram (two versions of this) and a victor circuit diagram. No information on the field coil.....resistance, inductance...etc. It will have to be rewound.

The wire of the coil weighs ~3 3/4 lbs and is about #32 so I can estimate the resistance (~3,162 ohms) the length is ~19,500'

Any ideas, leads, guidance.......thanks for any thoughts.

Jim
