No it is not true. All Sweet 16's had a gold trigger from the first year in 1937 when made available to the public. For starters, do you have a Sweet 16? Not all Browning 16 ga Auto 5's are Sweet 16's. Just as many standard weight 16 ga guns were made in that era as the Sweet version.
A 1948 gun may have or may not have the "scripted words "Sweet 16" on the left side of the receiver. If the barrel sn matches the receiver and the barrel band has 3 holes in it, then it's a Sweet 16.
Perhaps the reference about standard in 1952 is the fact that the cross bolt safety wasn't standard until 1952. Auto 5's had the front trigger safety until 1952, but there are a few exceptions between 1951 and 1953. FN still produced some Auto 5's with front trigger safeties into the 1960's for markets outside the US and Browning.
Browning converted many front trigger safeties to cross bolt safeties at their shop in St. Louis. It's possible that if you have a Sweet 16 made in 48 and your safety is a cross bolt, then that would explain the blued metal trigger.

It always had one from the beginning when they were introduced in 1937.
Under trigger
A 16 ga Auto 5 was made with that serial number in 1929, but it was not a Sweet Sixteen. Sweets were not made until 1937. Does your gun have a letter above the serial number or preceding it? If not, does the gun say Seet Sixteen on the receiver and / or have a gold trigger? If not, then your gun is the standard weight gun made in 1929. Auto5man
Not standard.

There were a few that do not have a standard trigger, but use a THUMB trigger. Do a web IMAGE search for Winchester thumb trigger rifle, and you will find it.
depends on what year you have but most likely it will however, the rocking trigger is not an improvement over the standard spyder e-trigger so it is usually better to save some money and go with the standard e-trigger
