I've mentioned before that I've kept a spreadsheet of which Dixon marks appear on which plaques. The evidence suggests that the 'Dixon, Phillips and Co' anchor mark was used between 1834–1850. Whereas the 'Dixon Co' mark was used from 1851–1865. See the new Plaque dates page for more details.
The plaque above, recently sold on eBay, is the first circular plaque I've recorded with the anchor mark. It seems likely that it was made in the late 1840s. We know that Moore & Co were making similar circular plaques with 'Sporting' scenes about that time.
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.
