Should the serial numbers on the receiver and the barrel match on a Browning Sweet 16?

Prior to WWII all barrels and receivers should match. The practice stopped as absolute in the late 40's to around 1951 or 52. It is not necessary for them to match to be original as sold, however there are many cases where a barrel did match a gun as late as the 60's. This does not affect the value or collectability of the gun after the 1940's if it doesnt have matching numbers.
