This is the DUST Tactics 1/48 Horten HO-347 "Der Adler" I picked up several months ago for about $12. It's kind of a rough kit designed more for gaming than for fine scale modeling but I love the overall aesthetic of the plane. It's very much in keeping with German Luftwaffe plane designs while also incorporating more "high-tech" Dieselpunk ideas.
