I recently acquired a quite dirty shelf clock with a label R W Patterson Canada West ( a term in use from 1841 to 1867). The Canadian Clock museum states that "clock pedlars" operating in Canada in the 1850's imported movements made in the USA and placed them in locally made cases. This movement is geometrically identical to the Seth Thomas #80 but the dimension are somewhat smaller than those listed by Duy Ly (vol 2, page 955.) The movement has no i dentifying stamp. The case is 26*15-1/8*4-3/8 inches. It has cleaned up quite a bit but is still a bit of a mess. The overall black paint is chipped in one place to show a nice oak(?) column and there is no paint at part of the top RHS. I bushed a couple of holes and replaced the pendulum rod as the old one was a mashed up rod badly hammered to fit in the support slot. it is keeping quite good time. The mirror in the lower half of the door is very badly scratched but has what may be a signature in the lower RHS. my main questions are -is this a genuine Seth Thomas movement #80? should the case be stripped to what appears to be a nice wood grained finish ( oak?) should ( or can) the mirror be rejuvenated in any way? according to the Toronto second hand dealer the clock was in the family of a prominent family in Kirkfield, Ontario for over 100 years. Written into the dial plate, just above the central hole the name Lindsay, a town not far from Kirkfield, is barely visible. Another nearby name is not readable.
