old, Cold War vintage, US work blues wool sailor's uniform, jumper & trousers

Old United States sailor's work blues jumper uniform. This uniform is marked 100% wool. The jumper has a "US Navy - Contract #5664" label. The uniform pants have a 13 button flap and a "US Navy - Contract DSA-1-1129-63-C". We're not sure of the exact vintage of these, based on the military contract numbers, we're guessing mid 1960s, Vietnam War vintage.

The jumper for this uniform measures about 19" long on the arm (from the armpit to the sleeve cuff), 42" around the chest (under the arms), 17" across the shoulders and 24" long from the base of the collar to the hem in the back. The uniform trousers measure 28" around the waist and 28" inseam. There are a number of moth holes to the uniform jumper.
