I acquired this Jean Claude Constantine designed puzzle from PuzzleMaster. Made out of what I think is Paduak, the puzzle consists of a spark-plug enclosed by an orange coloured wooden frame with two horizontal metal rods running across from one side of the frame to other. The puzzle is slightly larger than a standard spark-plug and measures about 3 7/8 inches tall, 1 7/8 inches wide and 1 inch in depth. Overall the puzzle is relatively well made with a nice finish. The only complain I have is that the rods have some slight scratches and marks which I can't seem to get rid of. As to whether the spark-plug is usable, that unfortunately I cannot tell, although the spark-plug does look new and shinny.
The object of the puzzle is of course to get the spark-plug out of its framed enclosure. PuzzleMaster rates it as a level 6 and I agree. For someone with experience with puzzles, it is relatively easy to discover the solution; the kind of mechanism which is familiar and common to several other wooden puzzles. This is one of those puzzles which somehow I knew what to do the moment I unpacked it and managed to get the spark-plug out in almost a jiffy.
From a puzzling aspect, it does not provide too much of a challenge for any puzzle enthusiast. But from a display standpoint, I think it is a rather unique combination of wood and metal, and definitely will get a conversation started.
Calling all spark-plug manufacturers out there - Bosch, Denso, Autolite, Champion, NGK etc - use this puzzle to showcase your brand! But of course don't forget the royalty payments to Mr JCC.
