I wrote Remington with a partial serial number, 5 digits, found on the loading lever. Circa 1927/8 they changed the safety from the lever inside the trigger guard to a crossbolt behind the trigger. Model 11 20-gauge serial numbers began at 1,000,000.
) There was no serial number on the left side of the receiver. "The Sportsman" had a three-bird roll-stamping on each side of the receiver.
Browning designed, "Remington Autoloading Gun" in 1905.In 1937, Remington reduced the roll-stamping on "The Sportsman" to one bird on each side and started putting the roll-stamping on Model 11 receivers as well.
