It will be almost impossible to find something that was discontinued 4 years ago.

The hand scraping on the finish will make it difficult to replicate with unfinished birch. But you might have some luck finding someone who does that kind of work in your area.

Is there any chance you have 100 square feet in closets that you could remove to use for your repair, and then replace the closet flooring with something else.

Your problem today is why I have 75 square feet of 20 year old flooring stll in the box in my garage. Hopefully I will never need it, and hopefully it isn't ruined if I do!

Thank you for the response. We didn't originally install the flooring (it was in the house when we bought it) or we would have kept some. You were smart to do so!

Also, such a good idea to take it from a closet as we have some closets with it, but they glued it down. :(

It was a long shot and I agree - it is almost impossible to find. I think I will have to give up hope. :(
