I can't see the maker mark to the left of Sunderlin & Weaver, the retailers name. Sunderlin & Weaver are the retailer not the maker of the spoon. This site may help you with the initials, it is a nice list of makers by their marks, alphabetical with first letter of mark, when an american coin silver piece has initials like yours http://freepages.genealogy.rootsweb.com ... lindex.htm
