I have some used Armstrong Swiftlock Arlington Oak available... but I suspect it is Natural and not Antique... (My Lowe's receipt lists my purchase as Natural and my returns as Antique.) - Is your floor medium or dark? I am aware that there is also a Honey color which is very light.
I have two unopened boxes of this and another partial box if anyone is interested. 20.58 Square feet per box. I believe the "honey" and the "natural" are the same but you will have to verify that for yourself. Email me if interested. Thanks
