Charriere scarificator
Beautiful red silk and red velvet lined box containing a Charriere scarificator.  This "comb" design is much rarer that the common spring-loaded form.  An extra blade is present in a slot in the back of the case.
The manual scarificator has a series of removable blades on the center lock bar.  You would be able to place from 1 to 8 bars in parallel.  
Charriere makers mark on the back of the scarificator.
