I hadn't been aware of the varied interests of my readers. In response to several requests, my "knowledge" of the naval history stems from two books:
T.K. Fitchett, The Vanished Fleet (Rigby, 1976) and
Barry Pemberton, Australian Coastal Shipping (Melbourne U.P., 1979)
Pemberton's book contains a number of photos; Fitchett has executed meticulous watercolours of each vessel.
