The first place to look is Emaryllis.com. It has good photos and a lot of information about cultivars. I also go to the Plantscope website, which is operated by a consortium of Dutch growers: There are no Hadeco cultivars on that site. The Hadeco website also has photos of their cultivars, but its limited to what they are selling this year. I plant all of mine outside after their first winter blooms. About half have survived and thrived. Another quarter have hung on for dear life. The remainer have gone on to the Amaryllis afterlife. Outside they are exposed to all sort of nasty bugs, slugs and pathogens so only the fittest survive. Since the tags have all faded out, each year I can be surprised by what blooms. I don't sell or trade them. I still think you should email Florissa Co with a photo. See if they recognize it. It may be something else they sold, and the bulbs got mixed up there or when they came from the grower. The worst they are going to do is ignore your email.
