A patent is a grant from a patent office, such as the United States Patent Office. "Patent Pending" is a phrase that an application for a patent has been filed and is in some stage in the process of obtaining a patent. Thus, a patent can be presently enforced while a patent that is merely pending is unenforceable but can mature into a patent that can be enforced. Once the pending patent matures, the patent owner can sue for back damages or reasonable royalties starting from the filing date of the patent.
If that is a US Patent, you can look it up on Google, and tell when the patent was issued, but it cannot date the gun- other than we know it would have been made AFTER the patent was issued.
The patent date should be just in from of the bolt under the rear sight. But only if it is a bolt action!!!!
