We have recently obtained a clock made by the Reason Manufacturing Company, Brighton, UK and patented by them and Thomas john Murday (UK patent 1326 in 1910). The patent can be downloaded by visiting the old patents page of the British library site and following the instructions given there. We are trying to obtain more information about these clocks. For example, were there any user instuctions provided to cover topics like battery life and replacement? What should the resistance through the coil windings be? What kind of battery was used when they were made in 1912-ish? Ours has thick brown paper stuck to the back of the dial, and I have seen one other that looks similar. Was this the norm? I wonder if there are other Murday Balance wheel clock owners in NAWCC and, if so, whether knowledge can be pooled.
