It doesn't have any markings on it. By chance, do any of you know what it is for? It looks like it is made out of copper.
Daniel, depending on the enquirer, I have a cheeky answer to the question "What's this off?" In your case that horn is off a 64 Mustang! You might then need to explain that it certainly isn't ON a 64 Mustang is it?
We do see lots of cheap copper and brass horns similar to that you show, usually made in India. They turn up in the cheap shops at different times. Some even work!

All the cheap Indian horns I've seen don't bother to put on a screen and they've been stamped India/Pakistan.Saw that back in the 60s from Pier One. Most likely off a horseless carriage or horse carriage. It could be off anything.
