Three small pieces of mission-used wire from the umbilical head of Gus Grissom’s Liberty Bell 7 space craft. Pieces measure about .75″ long. The umbilical head provided all electrical power to the space craft up until 30 seconds before liftoff, when it was ejected from the receptacle and the craft went onto its own internal power. Accompanied by a 2003 letter of authenticity from Rick Boos, who states, “This strand of wire was removed by myself from within the flight-used MR-4 ‘Liberty Bell 7’ spacecraft umbilical head on February 25, 2000. Said spacecraft umbilical head was obtained from Launch Pad Leader Guenter Wendt by myself in November of 1993…Only two spacecraft umbilical heads were salvaged during the entire Project Mercury program. Al Shepard’s…and the MR-4 plug that Guenter Wendt kept for his own collection until he sold it to me.” In fine condition. RR Auction COA.
