WOW machines are a stretched 201 but they lose the 201 look in the process whereas the homesteader retains that vintage singer look.
WOW also stretches many of the modern 9 inch throats (juki, janome, brother, etc) the cost is $1,800 and the wait list is 40 people deep and takes about 16-18 months from when you get on the list to when your name is called.
the final result of a stretched 9 inch is an 18 inch machine - you lose the feed dogs completely and the needle up/down and thread/cutter is moved to the top head position.
