Unidentified 4 - Chesterfield/Brampton or Denby ?

Click on any segment to magnify it.
There are two series of jugs from this maker.

Uniformly dark salt glazed jugs with almost black sprigging. Half to six pint sizes recorded, all with greek key design around the shoulder and with or without grape vine sprigs on neck.

Cream coloured jugs with light brown neck and the same dark sprigs as other series. One, two and three pint jugs seen.

They must surely be from Derbyshire but are they Denby , as suggested by Graham and Alva Keyes in their book "Denby Stonewares", 1995 or from Brampton/Chesterfield?

All have the same handle terminal of ears of wheat, not seen on regular Denby products. Although the body sprigs, particularly the windmill and vicar and clerk appear to be the same as on many Denby products, closer examination shows most to be different.

Recent discovery.
The very unusual sprig of a fiddler playing to a caged bird on this 5 pint jug dating from the 1890s also appears on the dark coloured 5 pint jug. Its shape and colour scheme would appear to confirm that Unidentified 4 is from Brampton/Chesterfield rather than Denby. This sprig has been described as representing Blind Jack of Knaresborough, the extraordinary John Metcalf (1717 – 1810). Wikipedia: https://en.wikipedia.org/wiki/John_Metcalf_(civil_engineer) Although Metcalf did make his living, when young, by playing the fiddle, I haven’t seen any contemporary image to confirm the attribution.
