Tall Antique Hardwood Bookcase with Secretaire Below 1910s

Very tall antique Edwardian hardwood, probably walnut, dresser with glazed two door top having three adjustable shelves inside, above a cupboard base with two carved panel doors and shelf inside. A large drawer in the base opens to reveal a secretaire section: the front flaps down when two brass buttons are pushed, and becomes a writing surface with inset skiver. At the back is a fitted interior featuring four small drawers and various cubby holes. Made around 1910 probably. The top has a working lock and key; currently the base doesn't but the doors stay shut. The top and base come apart (thank goodness...) and there's a separate cornice on top.
