Yes, Chris, I concur with Kirk. It looks identical to my late '39 (NOV) s/n *9N-653I* model as shown in the pix below -the blue one. If you are just looking for a used original diffy case to replace you busted one, I know of a 9N parts tractor near me that would work for you. You know my contact info...
