Lunar Module Ascent Engine Cover Shield Assembly. Aluminum plate, anodized a striking red color, measures 23″ in diameter, and engraved with “Caution Step With Care,” and “Remove Before Flight,” as well as two lines of instructions near the top. Part numbers on pads on the reverse side have been evenly worn, probably from use. Cover is signed in silver ink by James Lovell, Rusty Schweickart, Dave Scott, John Young, Buzz Aldrin, and Edgar Mitchell, each adding their missions under their signatures. In fine condition, with some expected scattered light surface marks. Accompanied by a print-out of a NASA photo of the inside of the Apollo 12 Lunar Module showing the Ascent Engine Cover at the bottom. A seldom-offered artifact, enhanced by the additional signatures of six astronauts who relied on the engines protected by this piece. Pre-certified Steve Zarelli and RR Auction COA.
