Brian’s Big Baffling Bolt (BBBB) - Brian Young

Absolutely wonderful SD puzzle by Brian Young, implementing 30 years of his ideas into the puzzle. A tricky solve, with some nice walls along the way, I must admit I required a hint at one point.

Solved once and reset. The bolt is in perfect condition (the brass shows some slight patina as usual), the box has a very small scratch-mark on the bottom (see pictures).
