1952 was the first year that FN made Brownings with the cross bolt safety as standard. I have seen a few guns made in 51 with the cross bolt and I have seen at least one 1952 gun with a front trigger safety. Many of the older guns were converted by Browning to switch the front trigger safety to crossbolt. You can tell this if there is a slot in the front of the trigger guard. If the customer paid, he could have a new trigger guard installed along with the conversion, thus it is not possible to date a gun by the safety alone. FN continued the front trigger on their guns that they sold worldwide until the early 60's. These were not Browning Arms Co. guns
1945

Yes to both questions.
Go to the Browning link attached to this answer. Be sure to print it out and save the drawing. Many people glue the drawing on the inside of their forearm where it won't hinder the barrel and recoil spring.
how do I change from mobile back to classic email
With this serial number it would have been made in 1926. If there is a letter above or preceding this number it would change the date.
It is both- the browning of the crust is a chemical change as well as any other browning. If the filling simply boils and loses moisture ,that is a physical change.
What Chevy Classic? Way more info needed to answer this.
It blocks off the magazine to allow the shooter to change the shell in the chamber without needing to empty the magazine or manipulate the lifter. The "classic" use was changing from a duck load to a goose load.
