[Milsurplus] R-390 or R-392 meters?

[H.W.Hall]

Happy New Year, everyone!

I have rediscovered a couple of meters, which I obtained at a hamfest a lot
of years ago. I believe they belong to either an R-390 or R-392 receiver.
Pictures of them can be seen at:

They both have the original mounting screws and the rubber gasket on the
back.
First question is: Are they both applicable to these receivers?
I'm pretty sure about the VU meter but the other doesn't look a lot like
I've seen in my research, though I'm pretty sure they both came from the
same chassis.
Second is: What might they be worth?
On Ebay they seem to have run from around $10 to $70 for just the VU meter,
but there were few auction samples to go by.
Thanks for the info...
