Any thoughts from anyone if it is original???

I was told many moons ago that the quick and dirty way to determine if an ammeter is an original is to check to see if it is painted black inside 'to hide the workins'. (see picture). Since his is not, I would have to say it is a repro. They can be checked without removal or disassembly. Quick check while perusing the Swap Meet or buying a used one.
