4-1/8" Unfinished White Metal Shade Holder

I love the shade holders that she has sell. You're the only online place that you can buy these vintage repops shade holders. But apparently all you have now are only 4 in. You do not sell 5-in shade holders of the same. Do you know how hard it is to find a 5-in shade holder vintage? Also you used to sell a smaller size I believe two and a half for a 3 in in the same style but you only sell those no more
