Good to see another Clock person here.
The photographs are of a "Matthaus Hipp Toggle electric clock "I built made entirely from scrap materials to see how low a cost you could build a time piece. The case was once a Mahogany door, glass from a failed double glazing unit, the Mercury came from a now defunct Chlorine plant, Brass from a local scrap metal merchant, Electrical components all from scrap industrial equipment. The most expensive items at the time where the four new Alkaline 'D' cells depending on the manufacturer keep it ticking seconds for between eighteen months and two years. It did keep me occupied in my workshop for a little over a year, it eventually turned out looking so good I decided to put a passing hour strike on a ex telephone bell and keep it rather than putting it up for sale. To keep it company I restored a "Fortin Barometer" found as a box of pieces.
