Meaning of "Hunky Dunky"

From the Online Etymological Dictionary:

hunky-dory (adj.) 1866, American English (popularized c. 1870 by a Christy Minstrel song), perhaps an elaboration of hunkey "all right, satisfactory" (1861), from hunk "in a safe position" (1847) New York City slang used in street games, from Dutch honk "post, station, home," in children's play, "base, goal," from Middle Dutch honc "place of refuge, hiding place." A theory from 1876, however, traces it to Honcho dori, said to be a street in Yokohama, Japan, where sailors went for diversions of the sort sailors enjoy.

I take it to connote a feeling of optimism and success; but it also has an outmoded and provincial tone.

Jonathon Green, Chambers Slang Dictionary (2008) has this very brief entry for hunky-dunky:

hunky-dunky adj. {var. on HUNKY-DORY adj.} {1950s+} (US) fine, excellent.

It seems worth observing that Green identifies five other hunky terms of varying ages in the same dictionary: hunky chunk (mid-19C U.S., "to steal food"), hunky-doke (1940s U.S., "in good/proper order; functioning as required"), hunky-doodle (1900s U.S., "fine, satisfactory"), hunky-dory (mid-19C+ U.S. "wonderful, Excellent, first-rate"), and hunky-peroodlum (1900s, "very attractive and sexually inviting").

Like Green, J.E. Lighter, The Random House Historical Dictionary of American Slang, volume 2 (1997) equates hunky-dunky with hunky-dory, but then lists two early occurrences of the term:

hunky-dunky adj. HUNKY-DORY. [Earliest citations:] 1955 Ruppelt Report on UFOs 119: Our vast files of reports are in tip-top shape; and in general things are hunky-dunky. 1981 Louisville, Ky., man, age ca50: Now everything looks hunky-dunky.

A Google Books search turns up this item from Brown v. Republic Productions, Inc. (September 14, 1945), in Reports of Cases Determined in the Supreme Court of the State of California (1946) [combined snippets]:

SCHAUER, J. — The controlling issue in this case is basically the same as that of Brown vs. Republic Productions, Inc., ante 867 {161 P.2d 796} [1945], our opinion in which has been this day filed and reference to which is suggested for a statement of pertinent facts. The cases may be said to differ only in that the findings established that the extent to which portions of the original compositions were incorporated in the revised productions is substantially smaller here. The musical compositions involved are five: "All This and Heaven Too," "Peek-a-Boo," "I Could Love You Any Time At All," "Hunky-Dunky-Dory," and "Bonita Lolita."

And even earlier is Samuel Adams, The Gorgeous Hussy (1934) [relevant text not visible in snippet window]:

"All hunky-dunky-dory-o. She'd like to see you."

"I'll bet she would!" snickered Tony, with an obscene leer. Roderick Dow, Esquire, straightened his spare form. His face was dark.

"Did I ever tell you about marrying a millionaire-lady, Eb?"

These very early instances suggest that hunky-dunky originated as a nonsense extension of hunky-dory (as "hunky-dunky-dory") that subsequently (but not often) got truncated to just hunky-dunky. The earliest match of all, however, may be a nonsense name on the model of Humpty-Dumpty. From T.P.'s and Cassell's Weekly, volume 2 (1924) [combined snippets]:

Hunky-dunky had no sense. Bought a fiddle for eighteen-pence, And all the tunes that he could play, Was "Sally, get out of the donkey's way!"

This rope-skipping jingle appears in the company of a number of Mother Goose–style rhymes along the lines of "Charlie Charlie sole the barley/ Out of the baker's shop..." Subsequent versions of the fiddle-buyer rhyme feature different names ("Dancing Dolly" [1977], "Charlie Chaplin" [1982], "When I was young" [1990], and "Pooka Sullivan")—and different songs ("Ta-Ra-Ra-Boom-De-Ay" and "Over the Hills and Far Away"). In fact, the original personage in the rope-skipping rhyme seems to have been either Polly Perkins, who appears in "A Village Sovereign," in The Living Age (September 11, 1897), or Dancing Dolly, who appears in the version recorded in Alice Gomme, The Traditional Games of England, Scotland, and Ireland, volume 2 (1898). "Hunky-dunky" doesn't appear in any other version of this rhyme that I've seen.

Watch Christmas in Connecticut (1945). (A transcript of the movie can be found here.) I guarantee that any widespread use of “Hunky Dunky” started with that movie. It’s a classic in language alteration. Felix Bassenak, played by S.Z. Sakall repeats the phrase “everything is hunky dunky!” two or three times. Also listen for how he butchers “catastrophe.”

Maybe a clue is a possible derivation of a cartoon film about donkeys :

Hunky and Spunky are fictional characters, appearing in the series of animated short subjects produced by Fleischer Studios for Paramount Pictures from 1938 to 1941.[1] Filmed in Technicolor (three-strip), the series revolves around a mother burro and her son.

History

Hunky is a mother burro and Spunky is her young son. The initial film, titled Hunky and Spunky, takes place in the Old West, where a prospector attempts to make Spunky into his pack animal. Hunky and Spunky was nominated for the 1938 Academy Award for Best Short Subject (Cartoons).

Fleischer Studios went on to produce six more cartoons featuring Hunky and Spunky: Always Kickin' (1939), The Barnyard Brat (1939), A Kick in Time (1940), Snubbed by a Snob (1940), You Can't Shoe a Horsefly (1940), and Vitamin Hay (1941). The series ended in 1941 with Vitamin Hay.

After Famous Studios succeeded Fleischer Studios in 1942, they revived the Spunky character alone for three cartoons in their Noveltoons series, Yankee Doodle Donkey (1944), Boo Kind To Animals (1955) and Okey Dokey Donkey (1958), with the latter featuring a simplified drawing style.

A positive contemporary review of Hunky and Spunky in Film Daily praised the short for introducing "funny new characters", and stated that the short's device of having the animals speak in "donkey"
