Hi Joe, I have one that looks just like yours . (without the mice nest) . You have to call the Janome Co. And give them your numbers and they will tell you the year and where it was made. Mine was made in 1926 in Orange, Mass.
I think that was the last year that they was made in Orange. after that they moved, I think to Chicago. You can find out about the New home Sewing machine Co. online. Have fun with that one. Gloria
