The first 120 copies of the Doveltail burr from Frans de Vreugd were made by Bernhard Schweitzer -- a German puzzle collector/craftsman for more than ten years, with membership in the IPP (International Puzzle Party), a private, informal organization whose main objective is to promote and recognize innovative new designs of mechanical puzzles from around the world -- for his exchange puzzle ( made from Maple + Padauk wood) .

The model pictured above -- copied and fabricated from the original version by anonymous craftsmen -- was purchased from  Bits & Pieces online catalog .

Money Lock Bank
This is a very well-crafted puzzle !   A one-of-a-kind gem extraordinaire that comes along every once in a great while that doesn't seem to make much of a
' Here-I-am ! ' recognition .   However, those collectors who take special interest in these kinds of puzzles - as I do - can readily perceive the value of such a prized addition . . . and the genius behind it .
