The guy that made them was from San Diego and used to be on eBay under the name, RUSSIANRADIAL. He was somewhat of an eccentric individual and kind of difficult to deal with. I have not seen him list anything for sale for quite a few years now. The instrument is quite accurate when used in conjunction with a digital level.
