There is a font used by engravers called Gorton, but I could not find the equivalent TrueType font. Can someone tell me how difficult it is to create such a font given all I have is the font in an image?
If you plan on designing it from scratch you probably have enough image to work from. The font is very simple and straightforward design.
If you plan to scan it, the cross hatch design is a difficult background to eliminate.
It might be easier to look for similar fonts such as Engravers Gothic BT (Bitstream) or Gotham Medium (Hoefler) (these two are close) and look on Identifont (http://www.identifont.com/) or DAFont (http://www.dafont.com/), etc., for free equivalents.
These might be used directly or modified in Font Creator as needed.
