The phrase "Job Lot" is used in auctions to mean an often assorted quantity of something, for example a "job lot of bicycle parts" could be a load of tyres, wheels, handlebars, frames, chains, etc.
I figure that 'lot' probably comes from the 'lot number' in an auction, or from the fact that there is a large quantity (a lot) of the items. But what about 'job' – what does that mean in this context?

John Camden Hotten, The Slang Dictionary; Or, The Vulgar Words, Street Phrases, and "Fast Expressions of High and Low Society (1864) has a couple of interesting entries for job:
As Hotten reports, Johnson's Dictionary of the English Language (1756) does not provide an etytmology for job, and it offers these as the first two definitions of job as a noun:
Early occurrences of 'job lot'
One of the earliest occurrences of the term "job lot" turned up by a Google Books search is from a transcript of the case of *Cornish & Sievier v. Keene & Another* (January 30, 1837), a patent case heard in the Court of Common Pleas:
Also, from "Commercial Solicitors," in The North of England Magazine (May 1843):
And from "Narrative of Law and Crime," in The Household Narrative of Current Events (September 27, 1851):
It thus appears that a "job lot," in the first half of the nineteenth century, referred to a one-off batch of resellable items, often either of substandard quality or of odd quantity, and not always obtained from a well-established and legitimate source of supply. Then and later, according to Hotten, the term job retained a somewhat unsavory character, owing to its origins in the 1600s as a cant word.
But John Sangster, The Rights and Duties of Property (1851), and Henry Mayhew, London Labour and the London Poor (1851), describe the "job lot" market as constituting a full-time trade for a whole class of middlemen and purveyors, and as involving legitimate commerce.
