Your sticker shown is not original, I imagine it was a 2 sticker overlay from a sign shop. The font that is closest is Garamond, and that is what font yours appears to be but if you compare it to this original 1974 logo you will see that the S & C is different. The little kicker on the top of the "C" is not on the original and there would be one on the "S" too but rubbed off in your pic. I make my own at my dads house. He has a vinyl cutter and I use the Garamond font and when done I just take a razor blade and cut the top tips off of the S & C and it looks close enough for me. The top of the "f" is rounder at the bottom tip and there is other small differences but the S & C are the ones that stand out. There is some members up here that has the file of the exact original logo layout and you can take it to the sign shop and get a exact with that or he may be able to get something off the web to copy. There is a program my dad has that you can take standard jpegs or other picture files and run it and it will clean up the edges and un-pixelated it so the cutter will cut a cleaner edge around the letters. If you use a file just make sure you do this and get rid of the pixels so it will cut out cleaner.
