Reminds me of the ARR-5, 7  meter.
Any other ? The glass is broken. I opened the meter to remove a piece of loose glass that might damage the pointer. 
I "could" find a same size meter for the window glass and then put it on Ebay and wait forever. But it's more expeditious to offer it here as a project for you, postage cost only. I have not checked the meter electrically, but i can do that.
