Let's say, De Carle was "mistaken".I like the wag clocks, so I had a look at my uncle's 1975 copy of De Carle's Encyclopedia. His description of postmans alarm; 30hr; weight driven:circular dial; long pendulum..... and finishes up saying "usually of Dutch origin". no diagram is shown.
uncle wants to know if anyone has an up to date edition, and if the description has changed. Was De Carle wrong?
