Unique octagonal Meissen sugar box with KDP mark

With the rare mark ‘K.D.P.’ (Königlich Dresdner Porzellan?) and early swords mark in underglaze blue, Böttger Porcelain, Meissen 1722

The KDP mark is unique and not known on any other piece. It will have been used in experimental phase at the manufactory, shortly before the KPM mark was used in combination with the sword mark for sugar bowls and teapots.
