Given the dial a clean looking better but long way to go, there looks to have been a lot of work done on the clock over its life some better than other but this is always the case, the hood looks to be mahogony and the trunk and base oak the marriage of the clock has been thought of as it was not obviouse from the start, it is nice to have a grandfather clock thats been born as one but sadly this is not as easy as it seems as many of these clocks have been around for over 200 years and have been through many hands and a couple of wars, i have worked on a few that look like they had suffered a direct hit during one of these wars, also sometimes the origonal cases could have been the pine type which simple did not stand the test of time due to rot. The useual material is oak but there are many mahogony Longcase clocks about, these are sometimes more valuable than oak as mahogony is not indigenous to the uk , many Grandfather clocks where made to order so customers often picked the case materials and the clockmaker would instruct the cabinet maker, only the wealthy could afford such clocks and there was always competition between neighbours to who would have the best Grandfather clock, The clockmaker was often put under presure to make a clock just that bit better with more bells and whistles than the customers neighbour.
