Is there any way to repair a sealed, AC voltmeter (panel)? It is from
the 1930s and I would like to get it working again. The needle will
not move when voltage is applied, otherwise it looks fine.

It was made by John Reiner and Co. part # 12047

Tough search!

I believe this page leads to the company, that looks to be still
around :

I was unable to locate any parts, cross reference parts, or a website.

In most cases we would typically replace the voltmeter. If the meter
has an external input protection circuitry, you may want to start with
that. You can also be *bold* and try to force your way into the meter.
Most meter protection circuits are merely diodes and resistors, and
when damaged, can usually be found via a visual inspection.

I wish I could have been more help, and will keep my eyes open as I
search around in a few more places.
