Sizes: 22 x 8, 13 x 7, 15 x 12, 16 x 13, 14 x 5 s. This is set is a mash up of different European  marching drums. I wanted the set to be like a family; each member has something in common with the other members but also has some individuality. The common facors are: (1) All drums are tuned with a single tension system. (2) All drums have a metal shell (brass or copper). (3) Though not visible all drums are thoroughly re-worked. The were all cut open and fixed around firm wooden hoops that were in imperial sizes (originally the drums were in metric sizes). I did this (a) to have a large choice of heads to use and (b) to match the drums soundwise. Prize: sold.
