Researching more than the serial number? Read the Remington company and model history guide for the broader story of the manufacturer, its major shotguns, rifles, handguns, barrel codes and collector considerations.
Serial & Barrel Code
Left side of receiver & barrel shank
Use the full receiver serial including prefix/suffix letters if present.
First letter = month, second letter = year. The barrel must be original to the shotgun for the date to match the gun.
Try:
N642098V,
DB,
L123456V,
BW,
KP

Model 1100 filter: Remington barrel date letters were used before the Model 1100 existed.
This tool ignores pre-1963 matches so it does not report impossible Model 1100 dates.
Collector reference only. Serial and barrel code tables are approximate and may not reflect
replacement barrels or factory exceptions. A factory letter or qualified Remington reference is the best source
for production date, model variation, and shipping destination.

Barrel year code

the 1963-and-later Model 1100 production era.
Always confirm important valuation or legal questions with factory records, reliable Remington references, or a qualified historian.
