I had previously listed the Moore & Co plaque below as an 'Unidentified ship' on the Rare ships page.
Norman Lowe has provided photos of a plaque with the same transfer but titled 'Shortening Sail Off Helgoland'. Helgoland (or Heligoland) is a small German archipelago in the North Sea, which was ruled by Britain between 1807 and 1890 (see Wikipedia). The plaques were likely made around the 1840s.
There is a signature visible above the word 'Helgoland' in the title. This also appears on the untitled version, but is too small to read.
Stephen Smith lives in London, and is always happy to hear from other collectors. If you have an interesting collection of plaques, and are based in the UK, he will photograph them for you. Free advice given regarding selling and dispersal of a collection, or to those wishing to start one. Just get in touch...
