Presumably, 10n springs for Showa forks? If so, I have a pair doing nothing (also a pair of 9.5n). The 10's were from my '98 916 Showa forks - I changed them for 9.5n to suit my weight and then, after I fitted Ohlins to the 916, I fitted the Showas to my Monster which then needed 9n springs in them as it's a lighter bike. The 10n springs are the original Showa/Ducati parts as supplied on a new bike and the 9.5n are Ktech aftermarket. PM me if interested.
