Image 3 is a spare rubber shock mount. The one currently attached is deteriorated, so please use this spare. Overall, the condition is good. The exterior is probably a B rating. Operation has been confirmed with a Panasonic mirrorless camera. The sound quality is good, so it seems to be professional-grade. Please check the internet for details. The batteries used for the operation check are also included. They were only used for the operation check, so they still have plenty of life left.
