Hello, I recently bought an old audiometer (Realistic APM-100) (basically a panel meter with some other circuit board) and one of the Meters were well... "broken" from rust damage. I was looking around component parts websites and ebay and came across the exact same one
But was complete rip-off at +$20....
then looking at this one,
Since the lens its self is 45mm in dia I figured the meter inside would be about the same as the one I'm looking for
What I'm looking for is the Inside of the meter,the core of the thing its self (doesnt reallly matter about the casing), its about 23mm in width and needle is about 20mm long.
