23D Blimey O'Reilly! Took me forever to parse, even after help from the forum, because I didn't know that candle-making synonym. Incidentally, nor does the COD, which includes only the more familiar definition of the associated noun -- 'a dealer in supplies for ships' -- and no verb at all. Although if I'd bothered reading down to the origin I would have seen 'candle-maker'. Doh!
