The flooring you are asking about is from NobleHouse and is Model FC3418 and was a stock item from Lowes Home Improvment Centers, under Item Number 89184 But it has since been discontinued.
Even though I loved it and worked wonderfully well for all applications. I even went back to the manufacturer to find more of it... but it was the manufacturer who stopped making it.
It was 5" wide and 3/4" thick solid Oak.
Thank you for your interest in this project.
