Hi Carl,
it is difficult to recognise a typical type of font because there could be a lot of variations. In the past I could tell the type face by the look of it because there were some kind of standards. But with the aid of computer design nowadays you can create and modify your own. What I suggest, if it is that important to have that same font, if you have access to all characters then you can scan the printed characters and get hold of FontCreator. You can then import in say Photoshop and copy each character in place inside Fontcreator and create your own for future use. You need some tiime thou. I hope I have been of some kind of help.
