As you can see, a small cordeauz style terminator, 4 " X 2 1/4 " I believe it was made by New Zealand Industries, in 1956, and simply wish to confirm if these insulators usually had an extended inner skirt.

Most Cordeaux style insulators made in Britain had an extended inner skirt, only if produced before 1943, and a recessed inner skirt when produced after 1943.

A series of pictures taken inside the NZ Insulators factory shows extended inner skt Cordeaux style insulators being made in 1966. Thanks Lee

Simply trying to determine if this is uncommon or not. Thanks for any help
