Looking for current 1956 De Soto owner

[VMOlson]

We recently found the owner's manual for my grandfather's 1956 De Soto.  I know the family sold it years ago, but I do not know who bought it. More than likely he/she would like to have the manual. The car was from Powell, Wyoming, and may have been purchased on consignment from a dealer in Billings, MT. This probably happened back in the 1980's.  The car car number is 50 380 462.  My grandfather purchased it originally from Mustang Motors in Billings, MT.  If anyone has an idea as to who the owner is or how to track him down, please let me know!
