He peddled some upper run sporting weapons. He was born in 1837 and is listed by some sources as the nephew of Heinrich Barella. Leue shacked up with Fritz Timpe for a time, then on to Greener of Birmingham till at least 1907, some 10 years after his passing, and maybe had a partnership with Knoll on the side. So it depends on which date range within which the sporting weapon falls.
