U.S. government sextant specification


Subject: U.S. government sextant specification

The current U.S. government specification for marine sextants is
A-A-59005. It replaces previous military standards such as the one for
the Navy Mark 3 sextant pictured in my 1984 Bowditch.

Based on my military experience, I can't help wondering if the spec
was tailored to a particular manufacturer. The users want such and
such product, but procuring it by name isn't allowed. So they state
requirements which "just happen" to describe a product made by one
company.

The PDF document is only 15 k so I've attached it to this message.
