well, I'm not Geoff, but few amongst us are; here is the compleat OED entry, fwiw:

Obs.

[f. HUCKER n. or HUCK v.: see -ERY. Cf. also HUCKSTERY.]

The business of a huckster.

1377 LANGL. P. Pl. B. v. 227 She hath holden hokkerye [v. rr. hukkerye, hukrie; C. hockerye, also huckerstrye; A. hoxterye] al hire lyf tyme.


so, she has held the business of a huckster all her lifetime. the citation is evidently from "LANGLAND, William
The vision of William concerning Piers Plowman."

an additional aside: Mencken gives huckster as an American equivalent to the English coster, costermonger or hawker. maybe the latter bears some relationship to the obviously rare hucker ([f. HUCK v. + -ER, or back-formation from HUCKSTER, q.v. (Perh. only a glossarist's word.)] A petty dealer; one who bargains or haggles.

edit: I continued to be puzzlepated by "as used up here" until I realized that was just max being parochial again. I kept looking for previous usage examples from NZ here, which all seem to have been deleted.
