DSA vs NSN?

[jegrif-760]

I’m trying to determine the manufacture date range on an INSECT BAR NYLON so I don’t trash something which has historical/collectible value. It has a DSA number as opposed to NSN and my online search was inconclusive. The only info even close, showed 1963.

 

Any info or guidance is appreciated. Thanks in advance!

1966 based on this data from Bob Hudson

 

Military procurement was done through the Defense Supply Agency 1962-1977 and all contracts had a DSA prefix. The dates were by fiscal year...July 1 through June 30. Fiscal year 1962 had a DSA 1 prefix and E-62 suffix. 1963 and 1964 were the same but substitute "63" or "64" in the suffix. Fiscal year 1965 will just have the DSA 1 prefix and no date code. Fiscal year 1966 will have a DSA 100 prefix and no date code. Starting in 1967 there will be a DSA 100 prefix plus a two digit date code. So, for example, fiscal year 1968 contracts will have a DSA 100-68 prefix.
