Factory disc brake rotor question

Gonna leave the pair with hubs together and get them turned for sure, hopefully they are good. A pair of rotors bought and shipped is $130- 140 Cdn. Thats buying from Rock Auto or Summit. If I were to buy local it would be more than that. Ones with hubs gotta be worth a $60 gamble. Does anyone recognize what these extra hubs are from? You can see KH on the left one in pic.
Thanks
Steve
