Looking for seed or plants of M. lindsayi L1134 and L1135

Hi all,
I'm looking for (ideally) plants to buy of Mammillaria lindsayi Lau 1134 and 1135. I know that there aren't the real M. lindsayi, and they are now known as M. sinforosensis, but I would like to have these two to add to my collection of more recent collections.

I've scoured the seed lists without success as well, but if anyone has these plants and they have set seed, I'd love to have some to germinate and grow on.

Hi Chris,

I grew plants of Lau 1135 form seed that came from Piltz's about 5 years ago. I might still have the odd spare plant around. I'll have a look over the weekend and let you know.
I have never seen plants or seed of L 1134 either in anyone's collection or for sale.

Yours, Tam.

Thanks, Mark, that would be great.
