An inner disc froma four-part alnage seal for new drapery cloth.
See FIG.4. "Four-disc 'new draperie' seal found in London", Leaden Seals for Textiles - Some Archaeological Evidence Relating to Fabrics and Trade By GEOFF EGAN, Costume, 23, 39-53, 1989, "The development in the second half of the century of a range of mixed-fibre, lightweight, cheap textiles known to contemporaries as 'new draperies' coincides with a much greater diversity in the information given on some seal stamps. New draperies were first included in the alnage in the late sixteenth century, though subsequently there were sometimes delays while the appropriateness of bringing particular newly-devised fabrics under the regulations was debated. A few late seventeenth-century four-part seals have the generic legend 'new draperie' (Fig. 4), but others are more specific, giving the name of a particular kind of textile. ... 'New draperie' seals are known with dates in the 1670s."
Geoff Egan, 'Lead cloth seals and related items in the B.M. (B.M. Occasional Paper 93)' describes the term new drapery in the following way, "generic term for a variety of lightweight, 'cheap and cheerful', often mixed fabrics, which were developed in England in the sixteenth and seventeenth centuries."
