OK Mark, I'll play......
1.Chinese eye wrong location - should be:
2. Tank name Dakeyne should be either be white on black rectangle or black on the green camouflage
3. Squadron tac sign and callsign missing from NBC pack, turret sides and convoy marking. See below
4. Convoy marking - should either be black and white vertical stripes or should have squadron tac sign and callsign.
5. Unit Identification Signs missing from mudguards
6. Bridge classification markings and Union Flags missing from mudguards
7. Turret basket stowage includes a 5 gall can of oil OM-13. This was used to top up hydraulic start, main brakes and steering brake. From memory, I don't think we routinely carried OM-13 on the tanks. It was much more common to carry OEP-220 (gearbox) and OM-75 (Main and Generating Unit Engines).
8. Turret basket stowage - there appears to be a main armament obturator case in the basket. Mark - help here. I think we carried a spare set of obturators and given their importance, (they seal the breech end of the main armament), they were always carried in the turret or bins.
9. The thermal sleeve retaining straps are loose and sleeve is twisted
10. The cooker on the bazooka plate is a small Number 2 Burner. Tank crews were more usually issued with the bigger No 4 Burner. Some crews replaced them with Calor Gas civilian stoves but intense cold affected them and gas would not have been available in war, so the practice was discouraged. The No 4 burner was pressurised by a hand pump and could produce a spectacular firework display if badly handled or maintained. It was the duty of the last man on sentry stag before revielle to light the burner for the first brew of the day.
11. Random boxes on the turret. Not sure what these are doing there. The tank is fitted with the Solartron Simfire tactical engagement simulation system. It was utterly useless (we did the troop trials on it) and was rejected pretty quickly. The wiz-bangs and receivers are fitted but there should also be a whopping great laser projector unit mounted on the barrel. The boxes on the turret are probably the internal control and interface boxes which should be mounted in the turret in place of the ready-round projectile rack.
12. The long stalk fitted to the turret roof is the meteorological sensor for the Improved Fire Control System (IFCS was the first computerised system to increase gun accuracy). It provided temperature, pressure and wind data to the computers to calculate charge temperature and windage and make corrections. I believe it was only issued to one tank in a squadron and I don't think I ever saw it used or fitted.
13. No commanders machine gun.
14. Tow ropes missing
15. There are two water jerry cans, one on the ground and one in the basket. I believe we only used to carry one and a can of diesel. Chieftain was always short of stowage space.
16. Drivers sight wiper blades missing
17. Drivers mirror fitted but on the right hand side. The tank would have been in Germany and if it was fitted (which was rare), it would have been on the left side to show overtaking vehicles.
18. The road wheel hubs don't show any signs of being recently lubricated. The driver would always check levels on his daily parade and a small amount of oil would be seen around the filler ports. On this tank, the hubs are dry but the front left roadwheel has a big leak - time to call for BLUEBELL (REME fitters).
19. The Don 10 reel is empty. This is the cable reel in the turret basket which was used by dismounted crew to communicate with the turret crew via a handset which was connected to the end of the cable. The other end was terminated in the turret intercom system.
20. The ERM (Equipment Registration Mark or vehicle registration number) is in the wrong font.
21. The camouflage net in the basket wouldn't cover a maiden's modesty and was more normally stowed on the glacis, turret front or NBC pack. It was huge, as it had to cover the whole vehicle and was an absolute b*****d to set up in the dark in a wet wood.
However, not a bad effort for a civilian museum and good to see an attempt to portray the exhibit in context, something the IWM spectacularly fails to do in Lambeth.
Over to you Mark....
