   • 1851, Henry Mayhew, London Labour and the London Poor‎, volume 2, page 14:

     The pure-finders meet with a ready market for all the dogs’-dung they are able to collect, at the numerous tanyards in Bermondsey.

2. Used other than figuratively or idiomatically: see pure,‎ finder.

     As one commentator has noted, although a pure finder may "induce the purchase or sale of" a security within the meaning of Section 15(a)(1), he or she is not normally a "broker" because he or she effects no transactions.
