I’d like to ask about the sentence in The Red Circle by Conan Doyle.
The words are written with a broad-pointed, violet-tinted pencil of a not unusual pattern.
This is uttered by Holmes when he saw some pencil-written writings on pieces of paper. I’m not sure what the underlined part refers to, namely whether to pencil or to words themselves. In light of sentence structure, it seems the part refers to simply the word before, pencil. But I thought even Holmes, who can tell the brand of tobacco by looking at its ash (flakes), can’t tell types (shapes) of pencil just by looking at words with which they are written. So I thought in this case that the words are written in(/of) a font which is not unusual for printing, hence, the above sentence’s word order can be changed as..
The words are written of a not unusual pattern with a broad-pointed violet-tinted pencil.
Am I wrong? Could someone enlighten me? Thanks.
