m51 jacket - Contract No. 10631

[DubPablo]

Hi everyone,

I'm new on this forum and hope will not bother too much. I'd like to ask you about your opinion and potential confirmation what was the official last contract number of the m51 field coat/jacket. As the few last contacts from 1965 have only four digits, I found recently this one with five digits (got permission from the current owner to hijack/post pictures). Contract No. 10631 made by PHILA. QM. DEPOT in 1965 (and also interesting fact that on such a late contract number mil-spec points to initial mil-spec A. Is this the last contract?

Thank you for having look, I appreciate any information about this.

 

Regards
