I agree with you about the challenges, but she was very sure her's was a 13. I have been looking at my 13, trying to figure out how it could be done. It would be a challenging task. I'm thinking it may have been a modification done by a very clever prior owner, or else she was, as you stated, confused. I would like to see how it was done. She said they sold
it in Michigan, so maybe it is still floating around somewhere.
