I'm not sure how old these would be in current storage but I'm sure there are some really historically valuable models down to field service grades. I know the military was wrapping up their transition from the 1911 to the (worthless) M9 in the late 80's and completed other than a few small exception units by the mid or so 90's. I do not know when the last contract batches were made but many of the 1911's I was issued were definitely Vietnam era and earlier firearms. As I remember it from the armorers records anyway. Most of our issue were Colt, Springfield and Ithaca. There were other manufacturers through the years but I do not remember seeing any. As I understand all the Colt and Springfield's would not be an issue for California.
