Made after examples of the early 17th century.
The originals are in the possession of the Gemeente Museum at The Hague, and are said to be made in Vienna. The instruments have (as they had originally), goatskin tops.
The thin-walled, handhammered kettles have a 'trumpet bell' directly above the hole in the bottom.
This is consistent with surviving originals, but vanished in younger types.
A pair of these kettledrums are in use by the Bach Collegium Japan.
Dimensions: 21, 22 and 23 inch diameter.
