Up through the 1923 catalogue the Remington Model 11 is shown with the lever in front of the trigger safety. In the 1930 catalogue it has the crossbolt behind the trigger. I don't think Remington ever used the sliding through the front of the trigger guard safety that was used on the Browning A5.
In my 1938 Browning Flyer it says the "Sweet Sixteen" was first introduced in 1937. While a Standard A5 in 12- or 16-gauge listed for $49.75 with a plain barrel, the "Sweet Sixteen" listed for $65.75 with a matted barrel!!! A solid rib was $8 extra and a vent rib was $14.10 extra on any A5.
