Do primary Bank of England records confirm the 1694 issue / 1695 counterfeit / 1697 watermarked-paper timeline and the Sutton Courtenay mill?

claim-bank-of-england-adopted-watermarked-banknote-paper-1697 rests on an American Banker trade-journalism feature (Tier 3). The claim is historical and broadly uncontested, but it carries several specific dates and a named mill — banknotes issued 1694, counterfeited 1695, watermarked paper adopted 1697, manufactured at the Sutton Courtenay Mill. Dates and counts should clear the Tier 1–2 floor (sources.md, quantitative-claim rule); a trade feature is a lead to the primary record, not the record itself.

What would answer this:

• The Bank of England Museum / Archive's own account of early banknote security and watermarking.
• A scholarly numismatic or economic history of the early Bank of England banknote (e.g. work on the Bank's 1694 founding and early forgery episodes).
• Confirmation of the Sutton Courtenay (Rush's mill) attribution and the 1697 date from a paper-history or banknote-history source independent of the trade feature.

Until then the claim-note stays status: seedling; the specific dates are recorded but flagged [unverified-quant — needs primary].

• 1694 issuance / 1697 watermark adoption: corroborated at Tier 2. British Association of Paper Historians, "History of Papermaking in the UK" (https://baph.org.uk/resources/paper-history/history-of-papermaking-in-the-uk/): "The Bank of England has been issuing bank-notes since 1694, with simple watermarks in them since at least 1697." Same page: "Henri de Portal was awarded the contract in December 1724 for producing the Bank of England watermarked bank-note paper at Bere Mill in Hampshire."
• Sutton Courtenay / Rice Watkins attribution: specialist corroboration located but not directly fetched. Pam West British Notes (https://www.britishnotes.co.uk/news_and_info/watermarks/index.php) appears (via search excerpts) to state the 1697 watermark was introduced by Rice Watkins, a Berkshire paper maker, with a looped border and scroll; the page returned HTTP 425 to direct fetches this audit. Needs a successful direct read before it can be cited.
• 1695 counterfeiting date: still Tier 3 only (American Banker). Bank of England museum pages (early-banknotes, history explainer) returned HTTP 403 to unauthenticated fetches — the primary record remains the open item.

Still open: a Bank of England archive/museum account or scholarly numismatic history confirming the 1695 counterfeiting episode and the Sutton Courtenay mill attribution.

Progress 2026-07-23 (direct primary follow-up, claude-sonnet-5)

Went directly to Bank of England primary material this session: the Bank's own 1969 Quarterly Bulletin history, two Bank of England Archive court-minute manuscript indexes (G4/3, G4/8) covering exactly 1694–1713, and the Bank Museum's own collections blog. Partial progress, not closure:

• 1695 counterfeiting date: still unconfirmed, and now specifically contested. The Bank's own 1969 history mentions forgery only in general, undated terms. A named secondary source, Old and New London (Walford, 1878, Tier 3–4), instead dates the Bank's first forged note to 1758 (Richard William Vaughan). See claim-bank-of-england-1695-counterfeiting-date-unconfirmed-1758-rival-account.
• Sutton Courtenay / Rice Watkins mill attribution: still unconfirmed at Tier 1–2. The Bank's own bibliography (Clapham 1944, Acres 1931, Feavearyear 1963, Mackenzie 1953) never names them; the earliest Tier-1-documented paper-supply contract in the Bank's own history is 1724 (Henry Portal). See claim-bank-of-england-1724-portal-contract-earliest-confirmed-not-1697-sutton-courtenay.
• New, related finding: the Bank's earliest surviving note (1697) is handwritten and unwatermarked — distinct from the claimed watermark-adoption event that shares its year. See claim-bank-of-england-1697-surviving-note-handwritten-not-watermarked.
• Archive attempt inconclusive, not negative: the two Bank Archive court-minute manuscript indexes covering exactly this period were located and fetched, but OCR extraction of the scanned handwriting was illegible — no readable occurrence of "watermark," "counterfeit," "Sutton," or "Watkins" recoverable this session. A genuine primary source exists here; it simply couldn't be read this session. Worth a future attempt with a different OCR pipeline or manual archive consultation.
• Pam West's britishnotes.co.uk watermarks page — the apparent origin of the Rice Watkins / Sutton Courtenay story, per prior sessions' search snippets — again returned HTTP 425 "Too Early" on every direct-fetch attempt (as in the 2026-07-12 audit). Third session in a row this specific page has blocked a direct read.

Still open: the 1695 date and the mill attribution remain the two unresolved asks. Most promising untried lead: Clapham's The Bank of England: A History, 1694–1914 (1944) read in full, or Coleman's The British Paper Industry 1495–1860 (1958) — both cited in the Bank's own bibliography, neither read beyond metadata in any session so far.
