Hi folks!
I have acquired a very old car ammeter. It is brass and at the top of a circular panel about 9 cm in diameter. Under the meter are three push-pull silver knobs marked DYN LTS DIM. I would put a photo on here but I imagine the newsgroup does not take them. I am wondering what car it's from so I can go to the right newsgroups to offer it for sale. Must be rare. Someone may well be really hanging out for it!
