sorry Hyla, my response seems to have been obnubilated by my preconception that your definition was just an expansion of the literal French (handy-man). my definition should probably be considered a transferral of that original sense.

Cheval was a mailman (Facteur?) who (obviously?) knew nothing about architecture or building skills but nonetheless crafted the pictured ediface/artifact using his talents(?) as a bricoleur. it came up from a google of 'facteur cheval + bricoleur'. : )
