WILLIAM SLOAN & CO. LTD.

The first Sloan flag was a blue pennant with white W.S.Co lettering, the o enhanced and the other letters equal in height. It was also associated with St. Rollox, presumably through management. Griffin additionally assigns it to Glasgow & Bristol Channel Steamers and Dublin, Silloth & Isle of Man Steamers; Lloyds puts a dot under the o. Merchant Ships 1944 calls it the previous flag.

The later flag appears by Lloyds 1912. Brown 1934 omits dots after the letters; Brown 1951 and 1958 stop the diamond short of the edges, though Rosanoski assumes it was intended throughout. Brora’s photograph confirms funnel and flag, and a contributor recalls a broad funnel band. The National Maritime Museum’s example is dated about 1955–67 and measures 1117.6 by 1803.4 mm.
