The "Mark 5" has been in service since circa 1965, to the present day. It was introduced after the failure of the Mark 4. Therefore, it is the Mark 5 Unless you can prove that the Mark 5 has never been designated as "Mark 5" at any time during its long service life, then I guess we shall just have to agree to disagree. |
