Still looking for someone able to 3D print an insulator for me. It would fall under the CD 143 designation, but have a flared dome shape similar to the "Darth Vader" mold seen on some Brookfield 145's. Embossing would read (F-Skirt) WAGNER (R-Skirt) PATENT/ FEB. 25, 1908. It would also need to have a button top like on a 731.
