Locomotive Performance and Efficiency Test Bulletins (British Transport Commission)
These important sources of information typify "grey literature", and were technical reports produced for a limited circulation, but large sections were reproduced in the technical press and eventually copies appeared on the shelves of what was then the Patent Office Library. Ottley eventually listed them in the Second Supplement (numbers given). The earlier ones got into Jones. The authorship couild be given as British Railways or the Railway Executive. The publisher was the British Transport Commission. The title used is that given in British Transport Commission advertisements when they sold for 10 shillings per Bulletin. Information on the diesel tests comes via a NRM pdf file and via British National Bibliography online. Clearly some remain missing.
