I have attached two specimen pages showing Piquett Fence, one from an 1847 Eduard Haenel Specimen book and a second from an 1845 V. & J. Figgins Type Specimen Book, so it is possible that this face originated in Great Britain. It did not appear in any of the French specimens books prior to 1845 but it appeared in the mid 1850’s in France.
Thanks so much for the update, Robert! It turns out that Mr. Figgins naively named this face White—back in the 1840s, he had no way to know what the next five or six decades would bring to the Type World!
It looks like every glyph except punctuation and the numeral one exactly spans three “pickets.” Your revival specimen looks great without a blank one between them.
Did you try mapping the three-picket glyph to the spacebar? This is a giant plus because words are searchable. Furthermore, it needs zero digital-font typesetting expertise—any “dummy” can get a professional-looking result by intuitively pressing the spacebar. I suggested this idea to Alan in the thread about Cane Gothic (scroll to near the bottom).
Thanks again for your technical and historical expertise!
