Autograph — The claim that an autograph of El Cid survives dated to 1098 is not supported by widely-known historical canon; no such autograph is generally recognized by historians.
Die-cast toy — The claim that 'Matchbox' became a generic term for any die-cast toy car is an exaggeration; it did not become a true genericized trademark like 'Kleenex' or 'Xerox'.
Die-cast toy — The statement that 'Many die-cast manufacturers went bankrupt in the 1980s, including Meccano (Dinky), Matchbox, and Corgi' is inaccurate: Meccano (Dinky) went bankrupt in 1979, not the 1980s; Corgi did not go bankrupt in the 1980s.

Bumper cars — The claim that the largest operating floor in the US is Rue Le Dodge at Six Flags Great America, 6,455 sq ft is unverified and likely incorrect; the largest known bumper car floor in the US is typically cited as the one at Cedar Point (the former 'Dodgem' floo
Carousel — The first known American carousel is stated as being in Hessville, Ohio, in the 1840s, but there is no verified record for that location; the earliest known American carousels are generally attributed to New York or New England.
Carousel — The first American patent for a carousel is attributed to William Schneider on July 25, 1871, but earlier carousel patents exist, such as one by John J. Raser in 1850.
