I can’t do this for you. The photos are part of the description. I mostly sell older, used items – expect them to show wear and have some flaws. I try to give the best descriptions I can. It’s possible that some items may have unobservable or internal problems or damage that I’m not aware of. I do not completely disassemble items for inspection. I avoid using UPS. I try to charge as close as possible to actual costs.
