Check the scent, Fishermans Friend smells of cloves like a rugosa. It does look like FF to me.

The clove scent was a no-go. Only old rose in this bloom. I did notice that Othello has the same parentage, but it might take more maturing before I can really tell more. These first blooms can be deceptive :)

Thank you for your help, I'm sort of crossing my fingers that it's Fisherman's Friend and not Othello!

It could be an Austin, but it could also be a Romantica, like Rouge Royale.

The blooms on that one can have looser or tighter form, depending on weather or other factors, and it has nice big shiny foliage like your rose.
