Seller: kelly24_2008 (986) 99.1%, Location: Newtownards, Ships to: GB & many other countries, Item: 222329840717 Here I'm selling a mantle clock. I got from my grandparents loft and decided to sell. I'm not sure what way it works has hole in back which I assume is for a key but I don't have key. clock has Mark on top as seen on picture. lovely looking clock for someone who maybe has keys for this style of clock. it's a heavy clock so postage is £6.99.
