Gymnocalycium ID ......

[Maid Spikeion]

Hi, I've been trying to ID this cacti which is obviously a gymno ... I saw a photo in a book that made me think that it is G. Quehlianum, but I'm not as sure from the photos in google images. Does anyone know what it is? Thanks!

It's old so will be hard to match from a picture. Not sure about the colour reproduction, but the center of those flowers doesn't look pink?
