Grover Mini Rotomatic Tuners Style?

[O1218]

I recently came across a guitar I'm considering acquiring that has sealed Grover Mini Rotomatic tuners. The tuner buttons are attached with screws and I would like to swap them out with black or snake wood buttons. Is there a way to determine which model of Grover Mini , 202, 404, 505 they might be? Any help is appreciated. Thank you!
