Reporting question for Knob - Speed, Gibson Style see-through

Product:
Knob - Speed, Gibson Style see-through

Question:
RE: SKU: P-K542 Item ID: 039410 It says on your website that these are Gibson style speed knobs. Can you please tell me if they're designed to fit CTS short, split, fine knurled shafts? There are actually 2 types of speed knobs available at Stewmac: coarse for Aplpha Pots, and fine knurled for CTS pots. I just want to know which pot type item number: 039410, SKU: P-K542 is designed for. Thanks so much.
