As an SD puzzle it has many, many steps that are hard but not impossible. I believe it took me 5 and half hours to solve (I don't usually time myself but did because I was testing the design). Box, stand and instructions included.
I've always said that it would be amongst the last puzzles I'd ever sell and do so with a heavy heart, but unexpected bills mean I must let go this prized possession. I hope it finds a good home.
