Edited:
The nameplate of prop newspaper in the Sherlock Holmes move is an authentic reproduction of the engraved nameplate of a British newspaper called _The Penny Illustrated Paper and Illustrated News_. Compare to a letterhead from Nov. 5. 1881

I have not seen this particular lettering as a typeface. That is not to say that such a typeface was not made.
BTW the British Library announced in 2010 that this newspaper, and many others, will be available in digital form for online reading. Press release: http://blogit.realwire.com/british-library-and-brightsolid-partnership-t... and http://chnm.gmu.edu/worldhistorysources/w/276.html

Additional Information.
Unfortunately the links do not actually lead to the digitized newspapers.
By 1884 the idea of a concave lettering was made into a font by Marder, Luse & Co, which they called Concave. A version of concave was digitized as Show http://www.myfonts.com/fonts/juan-jose-lopez/show/ But there are considerable differences between Show and the nameplate lettering _ILLUSTRATED PAPER_.

Edited:
The second line of the nameplate is a simplified version of first line. Compare to the rather emaciated Gladiate

The _L_ of Herr Foch has a terminal treatment close to the _L_ in the nameplate.
Unfortunately IntellectaDesign does not provide information on the provenance of their fonts, which in the case of Herr Foch and most others, are autotraced from old specimens. Note the rough outlines
