Dave Scott’s flown data file clip carried aboard the lunar module Falcon during the Apollo 15 mission, 1.75 x 2.25 x 1, with a swatch of Velcro affixed to bottom and engraved ID numbers, “P/N SEB32100094–301, S/N 1070, Assy.” Commander Scott used this clip to secure equipment such as checklist sheets, flight maps, and any loose articles; it was most frequently used to keep his checklist book open to the right page during the crew’s 12-day mission to the moon back. In fine condition, with expected wear. Accompanied by a signed letter of authenticity from Scott, in part: “I hereby certify that the Apollo 15 Data File Clip included with this letter was used aboard the Lunar Module Falcon on the surface of the moon for 3 days during Apollo 15…This particular Data File Clip is identified in the Apollo 15 ‘LM Lunar Launch Stowage List,’ page 78. The traces of dark material in the velcro are most likely lunar dust from our space suits or other equipment…This Data File Clip has been in my personal collection since returning to earth.” A decidedly appealing and uncommon piece used extensively during the flight of Apollo 15, the first extended scientific exploration of the Moon.
