About a trumpet-shaped hippeastrum

[Victor Hugo]

Hi !!

I have had this hippeastrum for a few years but I don't know its ID. As you can see, it has a very nice shape and blooms in spring. I think it may be a hybrid of Hippeastrum doraniae. I got it at a flea market in my city.

I hope you can help me with the identification.

Cheers
