This is a treen container for a miniature brass spirit level (marked E. Preston). The treen container closes firmly. This is a delightful small tool that would make a special gift or part of a collection for the handy man. 3.5 ins (9cm) x 0.75 ins (2cm) x 3 ins (7.5cm). Weight 38 grams. This item appears in my book, “Antique Boxes, Inside and Out” on page 240.
