I'm planning to digitize this typeface, I was wondering if you have ever heard of, seen, or know any existing digital versions of it?
My quick searches have only found talk of a script called Splendid, so I assume that if this grotesk design has already been converted it might be under a different name.
In the old type sample book I found, 'Splendid Grotesk' exists only in this "extended" form and in three different boldnesses. In the book there is separately another grotesk called 'Accidens' [sic] so I don't think it actually is from the same family.
This thin extended Akzidenz grotesk [[http://www.bleisetzer.de/cms/front_content.php?idcat=57&idart=665|Here]] seems to come very close to 'Splendid', but is given away by the lower case 'e'.
Also, the bolder Splendids unfortunately not pictured here are even more distinctive from Akzidenz.
The Akzidenz also lacks this special retro grotesk vibe I find exciting and rare in digital fonts nowadays...which can also be a regional thing and common to unique finnish grotesks designed for an occasion in 1920-1950 or something.
