I have the exact same thing - a copper dipper with the same brass triangle on the front - I have found one other for sale, but the handle is slightly different - I have found the translation as Otto Mueller Miracle Lamp - but have no idea what it has to do with any of the Otto Mueller lamps - there are obviously more of these, and they have been made for a purpose, but what? They were made for some sort of liquid, as mine has been fixed with brazing on the seam on the back. A lady (Taylors antiques) has one for sale on Ebay in Florida, but she is calling it a Greek dipper for $US 299.99 - definitely not greek.
