Talk:Mercedes D.III

Source regarding similarities between Mercedes IIIa and Liberty L-12?
"the later system seems to have influenced both Packard's and Hall-Scott's engine designers to adopt a nearly identical "slotless" rocker-box overhead cam valvetrain design feature for the Liberty L-12 Allied V-12 aviation engine"

Similar language is in the Liberty engine page, which reads that the Liberty OHC valvetrain was somehow copied from the later Mercedes DIIIa. If it was indeed copied or otherwise influenced the Liberty engine's valve train, please provide your source. If the writer has simply noticed the similarity and made an assumption, the about quote needs to be removed as conjecture; likewise the similar text in the Liberty article. 2600:8805:8100:1C:433F:CE24:BCF7:D57C (talk) 11:47, 18 April 2023 (UTC)


 * Text was added in 2015 by an editor known to introduce unsourced original research, there is much more of it in the article ('may have', 'similar to' etc). The solutions are either to tag the text for source needed (which is pointless as there is most likely no source), add a citation (same problem) or remove the text. If I get time I will look at both articles and try to clean them up. Nimbus (Cumulus nimbus floats by)  12:37, 18 April 2023 (UTC)
