    Item arrived today. Shipping was quicker than expected. Packaging was up for the job, even though the box didn't fair well with the carrier the actual contents were so well bubble wrapped they were damage free. The item was very good value but unfortunately the shipping cost more. The item was the exact one from all the photographs and is almost new in appearance. A very good quality item., looks good. A great item from a very good seller. I would purchase from this seller again. Thank you.
