Not to be picky, but I guess it just depends on how you define "same kind." According to the Oxford Dictionary:
a class or group of individual objects, people, animals, etc., of the same nature or character, or classified together because they have traits in common; category:
It doesn't mean
identical. I suppose it boils down to how extensive you want to delineate "common traits." For example, you could say that a person who owns nothing but Smith and Wesson double-action revolvers has guns of the "same kind." I knew a guy who collected MGB sports cars. Different colors, different engines...but the same kind of car. I guy down the road from us raises Labrador Retrievers. Some are black, some are yellow, some are chocolate. But when "push comes to shove," they're the same kind of dog.
