    Item pictured and described very accurately and is in excellent condition. Packing was extraordinarily careful with double boxing to ensure safe arrival with no damage; packing and shipping were extremely quick. To summarize: a very, very nice item from an OUTSTANDING eBay seller with whom I’d be happy to do business with again! Thank you!
