[QUOTE="afantiques, post: 441779, member: 25"]Some rather dubious information from lecollectioneur. This is certainly a mid 18th C movement, the comment about the movement pillars makes no sense, this type of movement was replaced by the plated movement before the end of the 18th C. This one may even be a conversion from a verge escapement to an anchor escapement. The weights are from an eight day clock, you only need one and typically that would be 7 pounds, and usually lead. Using heavier weights is a way to keep a well worn clock running but will increase wear on pinions and pivots, the proper cure is bushing the pivot holes, if the pinions are serviceable. Very worn pivots mean the arbours need re-pivoting which is a much bigger job. Using the heavy weight will not cause immediate failure, it just means it may be too worn to work in 20 years instead of 100. The first source for makers is Baillies 'Watch and Clock Makers' and the second volume compiled later by Loomis. I have them around somewhere and will have a look for them later when I am up and about. There are many unrecorded clock makers in the provinces, and some provincial clock makers appear to have used multiple locations.[/QUOTE]
