Early Series 319 is similar but has a plain lip not wavy, and a more distinct transition from the body to the throat.
Four size variants are recorded; s and inch suffixes 6, 8 and 10. Except for the smallest size every recorded example has a handle. For some reason the handles found on this shape exhibit more variety of style than any other shape.
Height; 18.5 - 20 cm
Fancy handle shapes are found on 8 and 10 inch pieces of 317, and also 319.
One fancy-handle piece incised 317/10 appears to be a 319/10 shape and is catalogued there.
