I am in Fort Worth, until January 1st and then I get to escape back to the North. I was thinking that but the German treadle is a 15... and they look a little similar but do you know why the Cooper front. I got all of these out of an old museum... these are the keepers the rest have found good homes. I am going to the man's sisters house at the end of the month and she says she has paperwork on a lot of them but well I was curious now.
