This spacesuit has the designation A4-H, and was designed and manufactured for Hamilton Standard by the International Latex Corporation (ILC) in January 1965. It was probably one of the last suits made by ILC for Hamilton Standard under the first NASA Apollo contract for spacesuits. It was primarily used for carbon dioxide testing and shoulder design.

During the two-year period these suits were manufactured at ILC, extra components had been produced, and at the end of the production run, ILC made three suits principally from AX1-H through A4-H components. One suit was modified by ILC to their best/latest shoulder and arm technology, with the other two being delivered to Hamilton in December 1964. These two suits were subsequently modified, one by Hamilton Standard and the other by B.F. Goodrich.

It is believed that this is the suit modified by B.F. Goodrich, and was subsequently modified further by Hamilton Standard to include “Experimental Tiger” type arms. NASA Johnson Space Center transferred this suit to the museum after the end of the Apollo program.
