Windtunnel brushroll with hex ends

[k15]

I hope this is the right forum, I have a windtunnel 2 and am having trouble finding a replacement brushroll. Most I've found have square ends, but I need hexagon shaped ends. It's about 13" wide. Even if someone knows the part number that would help!

Do you have

A picture of the brush roll you have? I may have the replacement, inherited a huge box

I don't have it unfortunately, the vacuum was given to me without the brushroll. But I'm quite sure I have the right part number, it's 440003987. I added a pic of one of those.
