Before you do anything, we need to address that salvage value.

Except for a few uncommon things, Salvage hasn't been used for over 35 years.  Are the assets part of some of the unusual things that Salvage applies?  Or is it a REALLY old asset that was "placed in service" before 1986 (when salvage applied)?  If not, it was depreciated incorrectly, and the Basis is now $0 (but you may be able to file Form 3115 to 'catch up' on the missed depreciation).
