The first address known for Morley is 186 West Green Road, Tottenham, London N. In 1898 his address is given as 15 Brownhill Gardens, Hither Green, Catford, London S.E. and by 1910 as 325 Brownhill Road, Catford, London S.E.
Morley was responsible for many early works on revenue, railway and telegraph stamps, as author or publisher. His 1910 revenue catalogue lists his numerous exhibition medals, including Silver in Paris 1892, Gold in Paris 1894, Silver in London 1897 and Gold in Paris again in 1900, all for displays of Fiscal or Telegraph stamps. Morley also won many other medals and awards during his career.
He published, with Fred G. Lundy, The Fiscal Philatelist and Revenue Stamp Guide: a monthly journal devoted to fiscal collectors, which ran from December 1892.
In 1898 he and G.C. Lundy produced an Album for the Revenue Stamps of the British Colonies in two volumes.
Later, he was responsible for Morley's Philatelic Journal, A Monthly Paper For Collectors of Postage, Revenue, Telegraph and Railway stamps between 1900 and 1908 which was edited by A. Preston (Volume 1) and then Lionel Fulcher.
Morley was Vice-President of the Fiscal Philatelic Society until it ceased in 1928 and a member of the founding committee of the City of London Philatelic Club. Stanley Gibbons Monthly Journal for 30 January 1892 (p. 199) records his membership of the Amateur Stamp Collector's Club.
The Prince Consort essay
According to a report in The London Philatelist, journal of the Royal Philatelic Society London, Morley presented an example in black of the famous Prince Consort Essay to the Tapling Collection which is now housed in The British Museum. He also offered a copy for sale in the June and July 1902 issues of Morley's Philatelic Journal at a price of 50 shillings, ten shillings more than he was then asking for a mint Penny Black.
