Hurst shift box – no stampings?

Forgive my ignorance on this, but are all Hurst shifters stamped with the Hurst name and part number? Reason I ask is that I've got what appears and was said to be a Hurst shift box for my A833 but it isnt stamped "Hurst" and simply has the numbers 8118 stampted on one end and nothing else at all. Any comments on what I have here?
