Given the absence of the embossing, "Federal Law Forbids Sale or Reuse of this Bottle" - I would say the age in 1960s or newer (as in 60s or 70s)
It may be a Seagram's Crown Royal bottle, assuming the cap on this one is original to this bottle. See the similarity of the caps on these bottles on eBay: https://www.ebay.com/sch/i.html?_from=R40&_nkw=crown+royal+bottle+seagrams&_sacat=0&LH_TitleDesc=0&rt=nc
