Description

This is for a lot of 2 small weston meters-the blue box says audio output meter and the tan box says 0.5v dc voltmeter-they are both in original boxs and appear to have not been used but not for sure-i really dont know the exact age or much more than what is written on the box-the condition is very nice and clean-i bought and buy all of my stuff at local estate sales-i tried to buy things that were and are very clean-please ask if you have any other questions
