Between the time Hemingray used the Script style lettering and going to Prismic, they went through a bit of an evolutionary process that is somewhat unique to the No.9 and No.12

This photo shows what I have named the EVO 1 style. It is denoted by its deep cut engraving, much like the later Prismic style, but still retains the loose, handwritten look of the Script lettering.

Note the unusual "wide" "9". This is unique to this style and an easy way to spot them.

On left is an arc-embossed variant in crystal clear with yellow and purple swirls. On right is a more typically lettered variant in an off-clear / ice green with a little trail of olive in it.

To see an example of an EVO 2 [id=335238015] and look at the rightmost piece. This type has lightly cut engraving like the earlier Scripts, but in a very concise and linear style like the Prismics.
