Buick T-type And Grand National Performance

I know this isn't grand national related but I built this car a long time ago and have been looking for a while. But now that my mother has passed away I am getting desperate to find this car. She loved the car and was a lot of help in the building. She was helping us find it. Now I'm posting any where that will let me. If you know anything of it please let me know. May even offer a reward to whoever can lead me to the current owner
