Piston rings...
...or rather, not a single piston ring, let alone an oil control ring normally located below the gudgeon pin is in evidence in the sectioned view of the Merlin XXVIII engine in the 'Description' section. The left-hand cylinder shows very clearly the 'lands' between the machined slots where the rings are normally located (see eg diagram on p. 3 of "Potential applications of thermal spray coating for I.C. engine tribology: A Review"]), and compare to the top pic (oh dear, fatal scoring in evidence) and the bottom pic in the 'History' section in the Piston ring article for comparison. I'm slightly surprised that this caption has been included in the article (well done for the continuing GA status btw) for at least 13 years and not a single person has mentioned this fact.

 * I don't understand what the exact problem is that you are highlighting, is it that the upper piston compression rings are not mentioned? I've changed the description of the lower ring to oil scraper ring in both instances where it appeared and removed the second wikilink. There's a slight chronological problem with the length of the cylinder sleeves needing to be increased before introduction of the scraper ring which could be resolved with a footnote or adjustment of the text. The diagram in the pdf shows a normal ring layout, perhaps you are noting that the unusual position of the lowest ring isn't highlighted?

 * Hi, thanks for your swift reply. The caption says: "...featuring wet-liner cylinders and lower oil scraper rings..." but there are definitely no rings in the picture. It is obvious where the rings should fit, but there aren't any. I realise how much effort has gone into this article, I'm otherwise very impressed.

 * Thanks, I've amended the caption so that it is hopefully not describing the object in the image directly, could add that con-rods aren't usually painted white and two liners are missing etc, etc. I think it's fine for a general encyclopedia.

 * Great, that's much clearer. I recently acquired a copy of The Magic of a Name (2000) by Peter Pugh which includes a few pages on the R. The author seems to have been granted access to RR records: there's an extensive bibliography of "Works consulted", but no notes/refs at all. Would you class it as RS? My fave quote (not applicable here) comes from the beginning, re F.H Royce & Co. in Manchester and his business partner Ernest Claremont who lived over the workshop c.1885:
 * "Their only diversion at this time was a card game called 'Grab', which appears to have been a combination of all-in wrestling and strip poker. At any rate they both wore tightly-buttoned overalls when playing the game, which generally ended in their rolling around on the floor, fighting like a couple of puppies."

 * Yes, I have the three volumes of that book, they are used in many Wikipedia Rolls-Royce articles for citations, mainly biographies of the engineers and management staff. Nimbus (Cumulus nimbus floats by)  16:56, 22 January 2024 (UTC)
