Scales has a pronounced working class English accent. The Cape says to Scales, "... blue collar, public school guys like you..." Oddly enough, in England, 'public school' means an expensive and exclusive private sector school like Eton, Harrow, or Westminster.
Scales calls Flemming (in his silly cowboy suit) 'Fauntleroy'. The 1880s book 'Little Lord Fauntleroy' was incredibly popular in the US. Its pre-teen title character wore a velvet waistcoat over a puffy blouse with lace collar, a big floppy bow tie and short pantaloons with tight hose and a girly haircut. To some middle class Americans this just screamed 'wealth and status' and so thousands of American boys were forced by pretentious mothers to dress like complete and utter twits. Everyone made fun of them.
