Hi Bernard,
Further thought:-
This M&W piece has been designed with the metalbashers in mind, but I believe it to be dual-purpose as it works well as a stand-alone piece.

When Davidson made their glassware suites they made too versions of some items e.g. sugar bowls:- one normal and one 'to fit'. The later were designed for the 'metalbashers'. The differences were very small e.g. small change to the rim to make it easier to fit a silver or plated rim.
