Re: looking for Harris-Tarkett USA 5025 Red Oak Natural
Hardwood designs, and colors change with the wind. What was available when that floor was first laid and what's available today are two different things - literally. The T&G that is milled into the pieces has evolved over time, thicknesses have changed, materials have changed, etc.
Your best bet will be to take what you've got around to a few different shops and see what you can find that is close. A simple trick to blend the old and new together would be to use a different color in the hallway, or at least a border strip, then and match the original floor color as close as possible in the other rooms, this will separate the old and new colors which will be off enough to be seen.
