I.D. Help please

Ah now I can see it better, the one I have is a bit different. Nice plant though. Has it produced seed before?

This is the one I have. I suspect it is M. Magnimamma but I cant be certain until it flowers.

I think the plant above is Mammillaria polythele fma durispina, I bought a triple header of these plants at a Bunnings warehouse that was unlabelled.

This plant is very variable, but fma durispina has six radial spines, with the largest one being curved upwards and another large one being curved slightly downwards.

Thanks for the info SuperKabuto. I'll look into it a bit more but you very well could be right. (I had a hard time with this one so I kinda had a rough guess at it)
