What are the laws regarding inheriting patents?

How can you renew an expired patent?
Short answer, you can't. Not in the US, anyway.
If the patent has expired it means that the invention that was covered under that patent is now "In the Public Domain," and anyone can use, make it, produce it, etc. It cannot be patented again.
Trying to "re-patent" an item that once had a patent would likely end in a denied application. For one, the invention would no longer meet the Novelty Requirement of the patent process - it is no longer "new" or "different," and obviously has been known to the market for over a year (at least 20 at this point, actually). Even if your version were a new size or slightly different material, it still may not pass muster on the Non-Obviousness Requirement.
Patents exist as an incentive to innovation, offering the original inventor (or his assignees) an exclusive period of time to market, produce, and sell the invention, thus recouping the cost of R&D and (hopefully) profiting on top of it. Patents are not even renewable by the original holder, much less available for "re-patenting" by someone else who in all likelihood, if they're simply reproducing a product from the published patent claims, did not put the same research effort into the product's development.
That said, if you had an *improvement* or *new version* of an existing now-expired-but-once-patented item, you could follow the same patenting process as any other invention including conducting patent research, checking that you meet the eligibility requirements, filing and keeping up the fees, etc...

A properly drafted and issued patent can give you the exclusive right to make, use, sell or import something using or containing the invention that you have claimed in your patent. You can license people to do those things for you, or sue people who do those things without your permission.
There are other subtle reasons to file a patent, including giving notice to potential investors that you have confidence in your invention, to provide notice to other inventors that you claim to have invented something first (whether or not it is patentable), and possibly because your company gives a reward for filing patents.
To amplify: a filed patent also prevents anyone else from later claiming they invented it before you did, and generally prevents them from getting a patent on something that you already disclosed.
US patents have bar codes that enable automatic scanning devices to detect the bar codes, read them and interpret the numbers represented in the code, such as the patent or application serial number, thus allowing automatic handling of certain patent documents.

17 years from the date of issue, or 20 years from date of filing (priority date), depending upon what country it's in and whether it was issued or filed in the USA prior to 1995.

What is the value of a Remington Model 12-A last patented in 1919?
The Remington model 12 semi auto shotgun is going for 150-300 depending on the condition of your shotgun.
I believe that's not a model 12 shotgun they are referring to but a Model 12-A 22 pump rifle (with a round barrel). The value is GREATLY dependent on original condition, condition, and condition, a beater is $100 once you hit the 90% or so it's a $600 gun then the price shoots up based on condition as much as $1000 or slight more depending if you have the original box or not.
