I don't have a 1 inch ball bearing,  but I do have a 3/8 ball bearing.   I measured the rebound with that.   I dropped it from 10 inches, and got a bit over 8 inches of rebound.   Would the bearing size have a big impact on this test?   I was surprised to see that much rebound.  I bought this a few years ago,  I want to say I paid 75 or 100 for it.   The horn was chipped, I reshaped it some,   still not happy with its shape though. thank you everyone for your help with this.   

I'm pretty sure it's a Vulcan, but I'm not 100% sure.   It doesn't ring, but it does rebound a good bit with a ball bearing.  The thing that has me not positive is the serial number tag.  I can not see any legible markings on the sides.   Any and all help is greatly appreciated.
