[R-390] panel meters

[Shoppa, Tim]

I know it has been a good chunk of a century since I saw a truly fresh radium dial glow but I would describe it today as greenish-whitish. Don't know how much of the glow is the radium and how much is phospherence in the paint.

I think anything since the 60's is promethium or tritium.

A true repro/litho shop would be able to make jet-black transparency stencils (far superior to what you could do with a laserprinter or inkjet although, those might be good enough).

Quote: "I have the dial off of a R44/ARR-5. It is a thin plastic disk with a
black background and transparent MC markings etched (?) in.

Would it be possible to make such a dial face to fit both R390A meters and
have it backlit with a LED? What would it take?

Thanks for your thoughts"

I think it is a great idea. I think that the grungy finish on the existing
meters detracts from a really nice restore. You could even put a low powered
green LED in there to give a really sharp looking replication of what those
panel meters would look like when the radium paint was fresh and in a dark
room.

Now we need to find someone who can make plastic bezels and a negative
stencil.
