Looking for White Sweet Potatoes

A few years ago I grew a wonderful white sweet potato variety named "Sumor".  It was extremely vigorous and produced a large amount of white-fleshed potatoes that were not very sweet and could be used much as one would white potatoes. Since I preferred the more common orange-fleshed sweet varieties, I eventually quit growing it, even though it outproduced the others.  Now I'm living with a partner who is allergic to white potatoes, but can eat sweet potatoes and we are thinking that white sweet potaotoes that are not too sweet (like this "Sumor") would be ideal to try.  But I cannot find it anywhere online.   Just wondering if anyone is familiar with it, has some slips to share, or knows about any other varieties of white or nearly white sweet potatoes that are NOT sweet?

I think the "sweetpotatoblessings" site is using old information.  Steele Plant Company does not offer Sumor this year, and unfortunately being in California takes the SC Foundation off the table for me.  Another white or nearly white variety could work as long as it's not sweet.  But information on them is limited.  Right now I'm perusing Sand Hill Preservation Center's list.  They seem to have the largest selection of sweet potato varieties available mailorder anywhere, bar none.  I've used it to get my three standby orange varieties started (by looking through and picking out ten likely candidates, and then growing these out and evaluating them in my system, including the ease of propagating them from one year to the next whether by vines or by tubers).  But no Sumor!

Ebay had several white sweet potatoes (plants, I believe).  I did as quick scan earlier without finding Sumor. Beauregard might have been one of them.

I have had very good luck with plants on Ebay.

The 2017 Southern Exposure Seed Exchange catalog has 2 varieties. O'Henry & White Haymon. They show a purple variety too.

I have a bunch on my windowsill right now. Can't really tell you what variety it is, I got it from organic section at my grocer. I can share a few slips, just PM me .

The Hayman  sweet potatoes are white and were actually used as potato chips here in Virginia.
