Vintage PE set?
If you are in a modeling hobby long enough you collect all kinds of neat stuff. I ordered R&MM's script about 10 years ago, and I still have a few.
The left is Ferrari script set, and the right is Testarossa GTO set.
Here's a enlarged photo.
Also, if the body has a raised letter, you can try foil casting.
