Just purchase new ones. Sad, but happy to say. That has been my choice to have happened in my case a few times following behind my ex- father in law. What an ass he was, yes I followed behind him on those parts of life also, but the love of cars, boating, 53 foot house boat on the Tenn River, 19 foot god awfuls speed boat. 220 Merc on this no Lbs very fast boat. I have it up in the air walking. Scared to death. He had the 1st Trans Am with the Super Chicken 6.6 liter,,, in Chattanooga. So in college when he went out of town,, guess what I was doing with his toys,, oh yea. Just too easy to call the personal assistance if he was in town, and say can you have ever which car or boat gased and ready er me in 1 hour. Off I went to loose the memory of his daughter for 4 hours. He knew taking care of his bitch daughter was reason enough to let me have his toys when out of town. Other than that,, he hated me, but he was cool. Guns also.
