The Remington 870 Express shotgun was first introduced in 1950, and it has been produced in various models and configurations since then. The serial number of a specific Remington 870 can help determine its year of manufacture, as Remington has used a date code system for serial numbers. If you have a particular serial number, you can refer to Remington's records or online resources to find the corresponding year.

To verify a genuine Remington 870 Marine Magnum, check for the manufacturer's markings, including the Remington logo and model details engraved on the receiver. Inspect the build quality, including the materials used; authentic models feature a durable, corrosion-resistant finish. Additionally, examine the serial number for proper formatting and consistency, and verify it against Remington's records if possible. Finally, consider purchasing from a reputable dealer to ensure authenticity.
The serial number is located on the left side of the receiver, towards the rear, just above the trigger.
The Remington Model 1100 shotgun is still in production, hence it would be worth no more than list price - and probably less, if it has been used at all.
To determine the age of a Remington Model 870 Wingmaster 12 gauge with a 3-inch chamber, you need the serial number, as Remington's serial numbering system can help identify the year of manufacture. Generally, you can find resources online or consult Remington's customer service for serial number lookup. Without the specific serial number, it's impossible to determine the exact age of the shotgun.
