We don't know what the first knex gun EVER made was, but here is the first one posted on instructables: www.instructables.com/id/Basic-Knex-Cannon/

The basic cannon as DJ said was the first thing posted on instructables. Launchers of sorts were being made with record back when K'nex was probably first made and distributed. The K'nex company themselves actually had some sort of small gun on of the things in a book from awhile back.
Sorry, without record.
