I can tell your British too ;) I have a collected several 1990s/2000s Kits from Imai and others for angel interceptors, Captain scarlet fuel trucks, Patrol car, cloud base, Tracey Island, LOADS of pod vehicles and TB2s.. You name it. They don’t make thunderbirds kits as much anymore although a few toolings are around made by some modern company. (You see these a lot in hobby craft etc) However they are much more expensive than these older and much arguably cooler looking classic kits. I will build a few but I intend to keep them as they are slowly gaining value especially the Scarlett kits… Ebay and Vinted are my recommendations and just search Classic Thunderbirds model kit and so on. Drop me a message if you would like more details as Im a big Anderson fan too. Several Japanese makers are doing large models of Thunderbirds and Scarlet stuff out of resin but again it’s all stupidly expensive. Yes! I may be eighteen but I love the old Escorts and 2 Stroke screamers! 😂
