Ludlow matrices manufactured by the Ludlow Typograph Company are identified by a pattern of lines on the matrix "reference" side (the side you look at; opposite the casting side). There will be one line across the matrix on the bottom part of this side. This line indicates the size of the type body in points. There will be one or more lines in a pattern on the top part of this side. The pattern of lines here encodes the typeface. You will need a chart to read the code.
