We were digging a pond and found an old metal plate with the Ford emblem. It's about 2 in. by 2 1/2 in. Numbers are: 5E212 D9TE E4A NY-6 261. What is this? Is it a Vin number? It has 3 "ripped out" holes at both the top and bottom like it was peeled off of screws where it was attached to something. Thanks, Pat
