First welcome to the site. Hope you find the information and support you need for your restoration
With that part number likely no but it may look similar ( don't have one in front of me).
Appears in pictures to have the sharp outer edges with the sunken center with one attachment port originally
One example - not sure if the center markers/suppliers marks are correct on this one
Molded in white but of course painted semi-glass black with the rest of the mater cylinder and booster assembly before installation
