It's not much to go on, but enough to say probably a Dorfler & Jorka. D&J usually are labeled "Made in Western Germany," and they have different shaped posts from a Keilwerth. Keilwerth posts are like a triangle stacked on an inverted triangle (I don't know what to call the Keilwerth shape: like an hourglass except the waist bulges out rather than in). These posts are more rounded. Also the engraving is like a D&J.
