I came across this clock key for sale on eBay apparently for a clock manufactured by "Wales & McCulloch". They seemed to be a London-based firm with a shop at 20 Ludgate Hill. I haven't yet managed to track down who this McCulloch was or where he came from so it's still an unsolved mystery! Any further information about Wales & McCulloch would be gratefully received. And yes.. I did buy the key :) Edit: Aug 2021 Added a few other beautiful items found online, retailed by Wales & McCulloch: Pair of antique silver caviar trays in original box retailed by Wales & McCulloch A yellow metal Egyptian style brooch, with scarab beetle type insert in fitted case for Wales and McCulloch A mahogany clock by Wales & McCulloch Edit: June 2023 I found a photograph of their retail premises at Ludgate Hill, dated 3rd June 1906: Looking east down Ludgate Hill towards St Paul's Cathedral. Wales & McCulloch's retail premises can be seen on the far left,...
