Dear Sir or Madam,

I certainly would like to help but I only have the manual for the Non Lethal Miniaturised, Mk3, Nuclear Warhead. Likewise on page 1128 under the paragraph entitled "DISARMING THE DEVICE" it reads: "In cases of emergency and/or life threatening predicaments, take a large robust mallet and tap the shell`s dome 13 times in a downward spiralling motion, until you hear in this order, an elongated whir, 346 - 555 ticks, a very loud thud-come-pop, 2 bangs and a semi-silent hiss." It went on to say "If you hear the above sequence you will then move on the stage two.."

Here is where you may have a problem, there is an addendum page that fell out of the back cover of my manual correcting the aforementioned page 1128 which reads “WARNING Following the disarming instructions on page 1128 will place the missile in self preservation mode UNLESS prior to striking the dome 13 times the following procedure is preformed.”

1- Locate the spanner part number 5678 (13mm 5 pronged pin spanner, non-sparking) in your ordnance disarmament kit model 435B. Warning the spanner included with ordnance disarmament kit model 435B while similar in appearance to the spanner in ordnance disarmament kit model 435A must be used due to the longer pin at the 3 O’clock position to engage the disarming switch.
2- Insert spanner in the fuse retaining cover (Fig 29, page 11) with the handle facing the dome of the shell, rotate exactly 37.4 degrees clockwise, wait for three 1200 Hz tones and return the spanner to the upright position within 3 seconds. You may now turn the spanner three full revolutions anti-clockwise, wait for the hiss and make one more revolution back in the clockwise direction before proceeding with disarmament.

So I would say it looks like you may have put the cart before the horse as it were by tapping the dome. I would venture to say this is exactly why the Mk2 and Mk3 warheads are so popular flea-market items having been disposed of by the military due to the confusing nature of the manuals and manufacturing defects in the ordnance disarmament kits.

I would say Thunderbolt the 15th is indeed a lucky kitty as his demise will not include being blown to bits by your Mk2 should it go into failsafe mode.
