Please check the catalog on-line. I have some about 3" tall I got from The Depot about 15 years ago. They also have some plastic numbers that are faced with 3M reflective material. You can't miss those at night.
Im not sure if your question goes to H.Depot, I am just a local guide who doesnt work there, but they do have brass numbers. How large?? I dont know, but Id bet they have more than one size.
