He's done! After (more or less) 15 years, the one member I never had can finally join my powered Steam Team (in a way). It's near impossible to tell he's actually a Spencer in disguise, and he was well worth the effort. I'll even leave it as Henry by default since I would need him much more often (despite being more fragile than official engines). I got even more excited after managing to duplicate the coal and face, and it's the first time I ever tried it in practice. Apart from cases where I don't have a suitable moulded face, this is how I'll make them from now on. Only the eyebrows didn't quite turn out how I expected, and I forgot one boiler band since I (still) tried to base him on Gordon's proportions. One disadvantage is the wheel stickers don't make him roll very well and the right front one is a bit off, but they still do a good job. I would've used Custom TrackMasters tender stickers if I were allowed to buy them, but I had to get them from a side photo of the TOMY version instead. I'm highly impressed with the green spray paint I bought for him given it's close to Percy, though some areas turned out brighter/darker than others. For TOMY accuracy, the handrails and boiler bands will not be painted. Nevertheless, I got an exceptional result for my first scratch built piece of rolling stock, and I've gained enough confidence to build more replacement engines like this. For the interested, I've documented the full progress here. To finish off, here's the inevitable Three Railway Engines reunion:
(Sorry about Edward; I might make a new smokebox for him until I could fix the TOMY version).
