Just using google images, yes I get a couple of pics for Constoluto Genovese but a few more called Constoluto Florentino. This website has a good pic and it looks really close. We saved some seeds at any rate for next year.
Thanks for steering me in this direction.

I knew it was ‘Constoluto’ something, no matter what! Good sleuthing! Hope it produces true for you. :)
