Questions on a 1star General Parade uniform

[Laurent]

I bought this uniform for $310.- on E, sold as one from the 80s. After examination the cap is obviously an unissued piece but I was amazed that the date on the buttons of the tunic was 1963 (the uniform has traces of wear).

Here are some questions to which I'd like to get answers...

1) Is there anyway that this uniform could be not a "put-together"? :)
2) Were the caps in the 60s-70s very different from the caps made in the 80s?
3) Could this uniform have been worn in the 80s or a did a General automatically receive a new uniform according to the regulations?
4) There are some holes for the mounted medals on the tunic and the medals have been worn horizontally (same as the 1988 regulations). But the medals should not have been worn like the regulations from the 70s? (scan below).
