519  (500 Series)   Large vase.   

Does this shape appear in other series?  Probably yes, but unfortunately we don't know what the shape is!
Only one size is known but the use of the size suffix 12 suggests that other sizes may exist.

   Height; from inch suffix, approximately 30 cm

A contributor in the USA has sent a clear base pic incised Remued 519/12, but we have been unable to obtain other images - just the base. This is the only recorded example.
