I’m trying to find a source for Swedish GAB silver patterns from the early 20th century and am having no luck at all. I recently purchased a demitasse size spoon - it has Stockholm 1920 engraved in the bowl, and the marks for Sweden, Silver, Stockholm, and 1919, as well as GAB on the back. The pattern includes a bow at the end of the pointed handle and rays going up from a band about halfway up the handle. I just can’t find any source that will tell me what patterns this company was producing at this time. Any ideas?
