Egg shaped pinch pot Raku? Marked with a raised DB orBO?

A small egg shaped pinch pot - shaped like a large asymmetrical egg where the bird has broken out! About 10 cms tall. I'm not sure of the clay it is pock marked with little natural shaped holes all over. Looks to have been Raku fired and maybe burnished in places? It is marked with a little pair of raised connected letters that seem to have been applied to the surface of the pot - maybe a D and a B. Bought in an antique centre in Suffolk.
