showme it seems to me that starters that have a band going around the end of the starter case to cover the holes to protect the starter brushes like the one in DADS50 picture is a 6volt. And starter without the band and no holes is a 12 volt. That's how I do it when there's no tag on the side of the case. Yours look's like a 12 volt to me. Please fellow stovebolters correct me if I am wrong.
Thanks.
