I've found a wonderful resource that we all can use to help us match our lettering fonts to the prototype.

It's called "WhatTheFont", and it's located here: http://www.myfonts.com/WhatTheFont/

Simply upload a photo of the prototype you're modeling (make sure to crop it to emphasize the numbers or lettering), and it will recommend fonts to use to match it!
