Could someone please tell me what the designation "SK" on a Castello Sea Rock indicates? I have looked in the usual places for information including the articles on Castello designations and know that K designates size on a Sea Rock but I am not sure what the "S" means. Thanks in advance for any help.

It's one of those Castello mysteries. I've studied the SK's in my collection and at one time I thought it was a Hallco size code but then I saw a SK on a white bar pipe. I think all of mine are SR's or fumed top OA's from the 60's. It might be a short lived size code between the OA, B,C, SS era and the big K's. 8O
