A patent is active for its duration (generally counted as 20 years from its date of filing -- i.e., it's priority date), assuming all post-issuance fees have been paid. You can check with the patent office in the country where the patent was issued to determine its status in that country.

How old is a revolver with patent 51668?
A patent number will only tell you the EARLIEST date on which the device was manufactured, and the patent number could still be put on many years after the patent expired (although without any legal effect). For U.S. patents, go to USPTO.gov, click patent, search, and type in the number to find the image of the particular patent you're interested in (prior to 1976).
