I like the Tamiya Pibber patrol boat i built when it first came out 15+ years ago (i think)
i bought it at Mildenhall airshow and started it when i got home, its a great kit and so different to Armour, it was destroyed years ago but ive bought another and im planning on making an interior for it and basing it on the Pibber in Apocalypse now
other than the Pibber i would say the Kingtiger or the Jagdpanther, both from Tamiya
