Prior to WW1 the Brazilian navy acquired dreadnoughts of the Minas Geraes class but suffered from some buyer’s remorse. They sold the Rio de Janeiro / Agincourt. I believe they considered selling the Minas Geraes too, but I’ve never seen it discussed whether this was of concern to major powers while WW1 was ongoing. I would have thought the Royal Navy would have been interested in buying these British-constructed ships to support their initially modest margin of superiority over the Germans. Additionally (although this is a bit more far fetched) I wonder if there was any concern they could be bought by the Germans, especially post-Coronel. I can imagine a scenario where the Falklands goes slightly differently, and von Spee’s damaged cruisers are interned in South America but their crews travel to Brazil to man a reflagged Minas Geraes kind of like CSS Alabama. Even without the crews of the East Asia squadron, I believe that contemporaneously the Admiralty was concerned German merchant marine crews stuck in neutral ports could be refitting their ships to raiders - what if they tried buying Minas Geraes from cash-strapped Brazil? How does the Royal Navy react to a possibly operational (I believe the maintenance issues were well known) dreadnought in the South Atlantic when the surface naval campaign is most tenuous?
