I BELEAVE THIS CANNON TO BE BRONZE IT DOES HAVE SOME PATINA ON IT. THE WOOD CARRIAGE IS IN GREAT CONDITION AS ARE THE WHEELS. THE BARREL IS 9 1/2 ICHES LONG AND THE CARRIAGE IS ABOUT 5 INCHES LONG. THIS CAME FROM AN ESTATE SALE SOME YEARS BACK I NEVADA, IT LOOKS LIKE IT HAS BEEN FIRED. BUYER TO PAY SHIPPING & HANDLING. I always package glass items well, but once delivered to the post office I am not responsible for loss or damage, so I suggest taking insurance. The things I sell are old, vintage or antique in age and in many instances have been used. So please email me with questions in advance, so I will have sufficient time to answer or email you another picture or two. See my other Ebay listings for more Green glass.
