This capsule carried Wally Schirra. It is covered by plastic making photography difficult and is tipped on it's side to expose the heat-shield. The hatch-opening is also covered with plastic. The outer skin plate has been removed below the window: that held the painted 'Sigma 7' insignia.
This image from an earlier display period at the Johnson Space Center, Houston, TX. It appears that Sigma 7 still remains on this display stand, sans the cross supports. The same exterior shingles are missing as are those today.
