Hi Folks. Just joined. First post. Just stumbled on this site. I've been collecting time switches for many moons now. Mainly Sangamo, then Venner and Horstmann. My favourites being in that order. Oldest one is a 3 pin Sangamo with Solar Dial - over 50 years old and still going , all be it with a little gear train noise now ! On the subject of Sangamo's I noted an earlier post by Diove. Speak to the incredibly nice and helpful people at Sangamo. What you need is a Zone 3 (54 degree) or a Zone 4 (56 degree) dial depending on whereabouts in Scotland you live. (I'm a 56 degree man) £25.00p delivered then fit and forget ! Well worth the money. Prized exhibit is a yellow dial model. Only made for the 3 year (?) experiment of permanent BST. Spring reserve jobs and long discontinued interval timers - masterpieces of electro-mechanical engineering !
Venners of various types and Horstman's too. I could go on, but those at the back are already asleep !!
Cheers.
