I broke the hurricane style wall sconce, better wording?

Many lighting stores, like Lamps Plus, have catalogs with reproduction lights and globes. I found a white milk gl bell shaped one I broke off of a 1920's apothocary light. I literally took in the broken pieces not only to match the shape but to ensure I got the right size to fit into the hole, too. Call around to shops in your area that are lighting specialty stores to see if they have a repro catalog you can special order from.
