[R-390] Refinishing meters

[Scott, Barry (Clyde B)]

Has anyone experience with meters like the one shown at

http://members.aol.com/n4buq/r390a

I want to have it powder coated, but I'm not sure putting it in a 400-deg.
oven is a good idea.  Does it come apart?  It appears to have a hard-rubber
(neoprene?) gasket imbedded in the back.  Does this come out easily?  If so,
does it expose the method of disassembly?

I noticed that when I removed the electrical connections on the back, the
meter movement became loose inside the housing.  Apparently this isn't a
sealed meter and it should come apart but I havent seen any way to get it
apart.

...and, no, I don't plan on licking the insides of the meter...

Thanks,
