Can you ID a 32 Heavy Axle by its Hub?

[ModelAJim]

Guys, here is a pile of old axles, the one in the lower right where the hub has windows in it, is that definitely a 32 Heavy? Or did they make that style many years. Its been a while since I've been to this place and it was buried. Just saw a pick of a real 32 heavy and it had the same hub...wondering if its worth a trip back. Probably could get for hardly nothing. Thanks!!
