// A pirate spyglass extended: three telescoping brass tubes getting thinner toward the front (-y), each with a darker brass ring, a leather wrapped middle section and a glass lens at the front. It LIES FLAT horizontally on the ground (z=0), as a chunky toy-like item seen from above: tip/front toward -y, handle/back toward +y, centered on x, using most of the grid along y, at least 4-5 blocks thick so it reads at small size. No hands, no stand, no base plate.
