This is out of an Early Philco 16B Cathedral (121)

It differs than the one shown on the Repair Bench

http://www.philcorepairbench.com/tips/svctip01.htm

The Magnet is different.

The Coil checks good 825 ohms.

The Vane is free and moves easily.
I did oil it to free it up

It seems the Magnet has lost its magnetism.
No easy way to try to re magnetise.

Should I remove the Rivets ???
That way I can get the magnet out.
The Rivets are Brass, so i assume the replacement one have to be brass. ??

Anyone run into this Type of Shadow Graph?
