Any sunchoke experts here? Looking to positively ID the varieties I have

Hi all. I am on the hunt for some positive ID for the sunchoke varieties I have. They were sold to me with a name but I suspect that some are not accurate or have been mixed up. Attached are some photos.
I've tried to research on my own but there is very little information online or in books about these varieties. I suspect there is confusion about variety names since I found the following conflicts: This website lists this sunchoke (one that I have, Exhibit C) as 'Red Fuseau' https://www.nortonnaturals.com/products/jerusalem-artichoke-red-fuseau-helianthus-tuberosus but thi others website lists that same sunchoke as 'Aurora Rubin' https://gardensforlife.ie/product/jerusalem-artichoke-aurora-rubin-pre-sale/ . Not sure which is accurate

'Fuseau' I believe means 'spindle' in French, referring to the spindly long growth habit of the tubers without knobbiness of other sunchokes. I also have White Fuseau and it is very much smooth and spindly without knobs. The sunchoke I have though that was labeled 'Red Fuseau' (Exhibit A as attached photo) has medium knobbiness and is not very similar to White Fuseau. The sunchoke I have (Exhibit C attached photo) _is_ actually similar to the tubers of White Fuseau (spindly and not knobby); so perhaps this is actually Red Fuseau??

I am very confused. Any help would be greatly appreciated

Hi! I raise and sell about nine varieties of sunchokes including all the ones you've named here. I don't think you have any red fusueau among the ones you've photographed. The link on norton naturals looks like the red fuseau I know and love, although this year some of mine grew in pale! So weird. But such a truly lovely variety. Yes, the second photo -- the one from Ireland is also red fuseau. Not Aurora Rubin. I know this is just two tubers, but here's Aurora Rubin.

The Pink Crispy (photo 4) is accurate, at least it looks just like the pink crispy variety I raise. They are long, sometimes VERY long and great -- smooth, tasty, hardy, pretty. Wonderful.

I think the first one you have might be beaver valley purple. Not 100% sure on that, but it's definitely not Red Fuseau.
The second photo looks identical to another wonderful variety I grow called Red Rover. Those are so productive and such cute little jewels!
The third one I'm not sure, but I wish I had it. It looks nothing like the Pink Crispy that I have.

Let me know if you want more named varieties or want to swap!
