i did notice on the inside edge looks like a very light little imperfection almost a chip but not quite pic #2, its very hard to see and most would prob never notice it, but just want to describe accurate. not sure its originality? i don't see any make or def indentifiers? pretty neat though and im sure someone could repurpose and built someothing really cool. item will come as pictured, shipping is included for the USA with the exception of AK HI or PR will require additional postage, thanks so much for your business, hope you will have a great day!!!
