[R-390] Re: Refinishing meters

[David P. Goncalves]

Question: Does the joint between the circular case and square face have a
recessed metal ring with 4 notches in it? A couple of meters I recieved
yeterday have that, might need a special wrench to unscrew it, if it does
indeed screw in. It could also be a friction/compression ring; if so I
guess drilling into the notches would help. Just a guess.

Also: I was reading in the 'Pearls' about the solution of the meter face
reproduction problem (using a laser printer). I'd like to make a couple of
Fair Radio replacement meters into useable R390 meters, but to do so, I
need either a scan or high quality photograph of the two dial faces. Does
anybody have these?
