I say you try and fix it up yourself as a little project. I personally don't think sending it into Victorinox would be very chipper, but that's just my .2 cents. It still has plenty of life left.
I know that feeling - It´s the reason the nice refurbished old Camper now lives in Greece - I could not bring myself to using it and I am no collector (My Fiance will not agree, though).Hence teh steady flow of tools - Buy or trade, test and either keep in rotation or pass on....Nonetheless I´m curious what they can do for the old knife at Ibach.
