When this machine has featured in an earlier thread Mike Edge kindly pointed out some details I should have spotted earlier which needed correction, notably the safety vales and the chimney. He was also kind enough to supply replacements from his own kit, at a very reasonable price, and, following a second strip down, here is the state of the engine halfway through the paintshop. Note the improvement made by the new chimney.

A full list of the work undertaken appears below:

• Strip [phase 1] - Chassis put to one side, worksplates, driver and backhead removed and the body left in a jam jar of cellulose thinners overnight.
  
• Strip [Phase 2] - Having scrubbed all the paint away, remove sandpipes from underside of footplate (a silly place to put them and the were rather overscale) and then tackle all the other parts identified for replacement: dome/safety valves, chimney, smokebox dart (nice, but overscale), tank handrails (very soft brass and prone to bending, knobs also a bit chunky), remove filler cap, remove saddletank.
  
• Footplate mounted linkages (reverser, sanding gear) were replaced and this time, properly located into holes drilled in cab front and footplate. Experience shows that these things will, otherwise, go ping.
  
• Saddle tank - once stripped down and emptied of the PVA/Liquid Lead mix - a known expansion risk - it was aggressively cleaned up with emery cloth, wet and dry paper and even a large file to smooth the curves. Then cleaned-up, blackened and given a couple of coats of Halford's filler primer. This was left to dry for a few days, sanded and polished back and the tank filled with lead sheet and shot secured with epoxy this time and the holes for the handrails re-drilled. Only then did the new dome and filler cap go on. New handrails were only fitted after the first coat of primer went on. It still isn't perfectly smooth, but it's a lot better than what was there. The whole thing was then glued - more epoxy - back on to the boiler tube.
  
• New clips have been made for the cab roof and some more work has been done inside the cab (planked floor fitted). The sandpipes have been relocated to the chassis and have been chemically blackened rather than painted.
  

There's more to do - the whistle needs to go back on, not to mention more paint and weathering, but I've also taken the opportunity to revise the livery and to name the loco', mostly to show that work has been done. The lettering, applied using a very small brush, isn't yet finished - there will be a little more and I'm thinking about adding a drop shadow - and most of the white is there as an undercoat for red.
