Because it is such an early piece, it does not incorporate the hidden mouse, an inner carving, inscriptions, or any engraved hallmarks. There is a ledge in the base that supports the top unlike other pieces. Both have treble clef stamp on base.
Treble clef stamp on BASE indicates these pieces were made from July '95 to autumn 96. After that the stamp was placed on the lid. Available 1992 & retired Dec.1996
