History: FN has a long history of producing high-quality shotguns, with some models becoming iconic in the firearms world. Some of their notable shotguns include the Browning Auto-5, the FN Model 21, and the SLP (Self-Loading Police) shotgun.
Age: The age of a FN shotgun can be determined by its serial number. FN has used various serial number systems over the years, and the specific format can help identify the production period. Unfortunately, without the serial number, I can't provide an accurate age estimate.
Value: The value of a FN shotgun depends on several factors, including the model, condition, rarity, and market demand. Some models, particularly older or limited edition shotguns, can fetch high prices among collectors. For example, a well-maintained Browning Auto-5 from the early 20th century could be worth several thousand dollars, while a more recent production shotgun may have a lower value.
Identification: If you have the shotgun in your possession, you can look for markings or stamps on the barrel or receiver that may indicate the model and serial number. Some FN shotguns also have proof marks or other symbols that can provide clues about their origin and age.
Expert Appraisal: If you want a precise valuation of your shotgun, it's best to consult a professional firearms appraiser or visit a reputable gun shop for an evaluation. They can examine the shotgun, assess its condition, and provide an accurate estimate of its worth based on current market conditions.
