Czech Ceramic Pitcher, Odd 'Red' Glaze, Blurred Mark

This is 7 1/2" high, capacity is about a liter/quart; weight is ~22 oz. I get Czech, a wreath, Trade Mark, register...an' a crown with a cross (I think) in the gray stamp; also the impressed numerals 1720 or 1730 beside. The glaze color isn't red, but close; I can't put another good name to it...cranberry? The weird treatment of the color looks a bit like craquelure, but isn't...it is quite thin, as the wear on the corners an' elsewhere on the body shows. The black at the foot edge is uniform, as is the thin upper rim, but the handle shows brush strokes plainly. I won't guess about age, but hope y'all can shed light on what this is, for me. Thanks for lookin'!

YES! I saw the Coro.., but didn't make the connection.
So it isn't a Crown, it's a Coronet...an' an importer's trademark...from between the Wars. Thanks, Marote!
