Could it be Rosette Delizy?

Yes, of course it could be ´Rosette Delizy´. I will pass this information to my friend so he looks for ´Rosette Delizy´in HMF and check this out.
´Hugo Soller´rose is another option, and I think it even suits better with the attached picture; what do you think?

As always, my warmest regards and THANKS for your time!

To me, photos of the Hugo Soller rose show it more what we call high-centered.

The center of the mystery rose looks more globular in shape, like the photos of Rosette Delizy.

A closer comparison of sepals, thorns and foliage could also be helpful.

What else can I said!? An incomparable precision in every comment and extremely explicative. Once more: THANK YOU VERY, VERY MUCH!!!

By the way, have you had any news concerning the ID of the white blended rose from the other post?. I am very excited to know its name to add it to my personal ´Available Argentinian Roses´catalog...

Keep in touch, Mariano :)
