You are right it is a NOID plant, meaning it has no I.D. or petigree as a variety. So you'll never find it listed anywhere. But, you may find a few close to it (maybe close to the parent plants used in the cross)
But, it should never be identified as one variety, or another. Just enjoy it for what it is...different but, pretty! But, still a noid!

The African Violet Society of America frowns badly on naming a plant as a variety when it's not offically I.D'ed, or registered with The AV Society of America as such. And is considered dishonest to do so.

Your plant was probably one of a thousand random genetic crosses when grown from seed, and the breeder sold the rejected plants for whatever reason, but, usually becaue they saw it as genetically inferior for whatever they were looking to accomplish as a new variety.
So, the breeder sold them on the open market rather than destroy the whole crop of a thousand plants. Just for the sake of one or two plants for further cross breeding. (money, money money !)
So each baby plant is/was slightly different from it's siblings, yet still unstable genetically. they were they not named or registered! Which costs $$$ and time to do!
Even though each plant will grow, flower, and be healthy other wise, it's just not a named variety..

I once had an AV that was a named variety at the time, that had all white, with blue speckled flowers, and varigated leaves which grew this way for years.

Then SUDDENLY one day it changed!

It changed to all white, with blue speckled flowers, and varigated leaves on exactly half of the plant,
and dark blue flowers, and dark leaves on exactly half of the opposite half of the AV!
You could actually see the dividing line exactly down the middle of the two types on this plant!
Even to any flowers on the dividing line were half white/speckled and half Dk blue! Leaves, on the dividing line were exactly half varigated, half dk green!
It was weird to look at! But, so cool! That was back in the 1970's

BTW, The African Violet Society of America (or AVSA for short) has a huge A-Z research library of named varieties on they're website that you can research offical pictures, and discriptions of named varieties that are accepted as genuine varieties, and registered with them as such. You can become a member if you like for a membership fee, and they also offer an AV picture and discription data base on computer disc which has monthly updates that can be downloaded . Also for a fee.
The AVSA is considered the Hall mark of recognized varieties. And is the final word on AV varieties.

You can even breed your own type of new plant, or color combination, etc. and if you can get that specific plant's genetic's to remain stable for 3-4 generations from seed, you can then name it anything you wish, and register it with The AVSA.

There are local AV groups in your area you can join that will have AV shows, with plants, cuttings, seeds, etc. for sale cheaper than anywhere else! Also state wide shows with other groups in each state, America wide shows, and International AV shows, and expo's. just like dog or cat petigree shows, (but without all the barking, meowing, leashes, flying hair, and cages!)
AVSA will have all that info, with pictures, and more on they're website for you! They may still have a seed exchange library still available free to members.
I hope that explanation, and information helps you.
