Dear RJLINDE,
Thank you for your inquiry. Unfortunately we lost all the records of this job durning a hard drive crash. The Owner of this home has since moved out of state. I did contact her but she could not recall the manufacturer. She purchased her own appliances and could not even reemember where she purchased from. There is a very similar model made by BEST K313936SS. Check it out here http://www.bestrangehoods.com/store/products/productdetail.aspx?id=5a983af1-91ec-4c4b-9700-09d9bb2a5dbb
