thanks playmo_80! that seems to be the exact same version of the ship my brother has.
Its a bit odd though that at the time with so much variation possible, the ship's crew and the add on pirate set have the exact same clickies who are equipped in the exact same way. Today's ships sure seem empty compared to this one, few items with it and never five clickies. Usually three or four with one being a child.
Construction worker mystery seems partially solved, the crate and one hardhat belongs to a bricklayer. Just need to find another set with a single hardhat now.
