It would be how the voltmeter would have been wired back then, you can damage the needle or it’s spring by pegging it for too long. Even then though, the only real issue I would forsee would just be the voltmeter spiking all the way to the right while it’s ringing, the chance of any real damage is pretty minimal. You can also check the datasheet on the meter, it should tell you what it can safely handle.
