[volt-nuts] Cool looking old stuff

[Joseph Gray]

I'm helping the local surplus guy by going through some old gear and
checking it over. Sometimes I find something useful :-)

I just took apart a Millivac Instruments MV-37B DC Differential Voltmeter,
mostly because I was curious to see what was inside (I haven't powered it
on yet). Most of what I saw was not very impressive, but one item stood
out. Take a look at the two pictures.
