Hi Tony, About 15 years ago I bought an instrument based on the Oughtred sundial as John Hall answered to your e-mail. This was built by Friedrich Tonne, Germany. The name of that instrument is horizontoscoop. I have a letter of October 1996 in which is written that the instrument is still for sale.
Institut für Tageslichttechnik Stuttgart Eichgehrenweg 3 70565 Stuttgart Germany The prise in 1996 was DM 329.- Not cheap for such an easy looking instrument, but the instrument is nice to play with. And please send me the picture you have. Happy dialling, Fer.
