Plate III

1807–1813
B.F.B. beneath a crown · impressed, without colour · engraved in the sourceChaffers 1891, p.723Chaffers states this one explicitly: 'Messrs. Barr, Flight & Barr, 1807 to 1813. The letters B. F. B. with a crown above, impressed on the ware without colour.' Impressed and uncoloured is the detail that separates it from a printed mark.
Plate IV

The full printed factory mark, including the London-house address set below a rule. Chaffers prints the address as part of the same block, and the cropper now keeps them together.

Why this differs from other listings
The Flight and Barr partnerships changed name four times in fifty years, and the mark changes with them — which makes a Worcester mark a date, not just an attribution. This entry keeps each engraving beside the years Chaffers gives it, and labels the two cases where the pairing is positional rather than stated. Listings that show the marks without the partnership dates leave out the only reason to look them up.
The source page

What this entry does not establish
- Two pairings are by position on the page rather than by an explicit caption, and are labelled as such. Chaffers dates B.F.B. and F.B.B. in words; he does not date every script mark in words.
- Chaffers 1891 does not cover twentieth-century Royal Worcester marks, including the date-code systems collectors rely on for later pieces.
- The Chamberlain works were a separate business from Flight & Barr until the later merger. This entry covers page 723 only; the Chamberlain marks are on pages not yet transcribed.
