Although the 1973 TEK catalog does list option 8 as a phosphor change, numerous instances (like the attached, undated product sheet) list option 8 as a protective cover. In fact, I own a 7603 scope with option 8 (sticker inside) and that is indeed equipped with a protective cover.
The 1974 catalog does not list an option 8 for the 7603 anymore...
It appears to me that the phosphor change option as listed in the 1973 catalog was too unclear and therefore later replaced by the options 13, 71, 72, 76, 77 and 78.
