    Air Ministry specification R.2/33 - Short Sunderland

    I'm on the scrounge. Does anyone have a copy , or just the key text, of specification R.2/33 that they would be willing to share? Failing that does anyone know whether the text of the specification has been included in any article or book, most likely one about the Sunderland. Thanks
