hello I am looking for engine room plans for rms strathnaver or her sister ship: strathaird, strathallan, stratheden or strathmore. thanks in advance.
Correct. The plans are also possible at the Greenwich National Maritime Museum. If the Poster wants just to see some basic drawings, The Shipbuilder. If he wants very detailed drawings then Vickers would be best and will coast a small packet.
Some small-scale drawings for Strathmore are to be found in "The Engineer" of 20 and 27 September 1935, which might still be available with Graces Guide.
