Does anyone know anything about the broken slash that sometimes appears in precomposed fractions – whether there was a clear first precedent, or if it goes back to metal?
@w__h_ the first time I recall seeing it was in Recursive but I wouldn't be surprised if it predates that
@sajatype @w__h_ Recursive is definitely post IBM Plex Mono, that is shown in the sample.
Let’s ask @boldmonday, if there was a historic example for this.

@justvanrossum @eWalthert @sajatype @w__h_ @boldmonday As @klim mentioned, the broken bar was common in Linotype Legibility series fractions at small sizes, usually aimed at stock listings.

I believe @frerejonestype picked up on this up in the original styles of Retina for the Wall Street jounral.

Here’s an interesting fraction approach from the 1923 ATF catalog that combines two separate pieces, each with part of the fraction. While not intended to print broken, you can see that sometimes it did. Which may have suggested the Lino Legibility approach to lightening that center convergence.

@kentlew Great to see this thank you
