I did find a manual at https://www.searspartsdirect.com/man...-machine-parts which includes similar machines and are not listed in the ID pdf. It looks like they are all low shank machines.

There is a Facebook group for vintage Kenmore sewing machines. I am not a member, but perhaps someone there may have better information.https://www.facebook.com/groups/680558488716580/
