Nice looking '49 Joe. Regarding the script... what's the VIN on the car (tag between hinges on the driver's door)?
If it's a K491, then originally it would not have had any scripts on the fenders as only the deluxe models had the color scripts on the fenders. If it's a K492, then it would have had the scripts on both fenders.
Restorers often liked to add those items (the scripts in particular) if and when they found them so if it only has one it may have been added like the hood ornament and bumper bar.
It's hard to tell from the picture if the car is a standard (K491) or deluxe (K492).
Regarding that and other items on it; it is your car so if you like those items on it, leave it as it is.
If your goal is to get as close to original as possible, then check said numbers first and that will determine what it would've had originally.
There's a lot of help available here in that regard.
