Product review (5 stars): Light Lens fits Nautilus Range hood fan perfectly!!
Whooo Hoooo!  Go Amazon!!  I just received this light lens part to fit my 15 yr. old Nautilus Range fan - Model NY-N and it fits PERFECT!! Even though it's a Broan part, the dimensions are identical to the one that deteriorated and crumbled apart. I will purchase another one as a spare. I asked the local major hardware store if they sold such a thing and he said "No." So I told him about Amazon.com and he was surprised.  Hopefully, he will tell others.  Thanks, Amazon!!
