The door tag is missing and I was told to look on the cross brace in the right rear corner. Is it located anywhere else? The brace is pretty rusty and I'm not exactly sure about the letters and numbers. I took a photo of it, maybe ya'll can see something I can't. Not sure about what the 3rd character is.
