Hi ~ your spoons were made by Horsens Sølvvarefabrik, their mark can be seen here:
Denmark H The company was founded in Horsens in 1904 by W.& S. Sørensen, unless something has changed recently, they're still in business, owned by Gense.
Just as a note, though you seem to know the history of these spoons and there's no reason to doubt their being original to the retailer's box, that's not always the case.
