While not really a public entity. Tamiya has been allowed to run a tiger, a king tiger, a pershing and a sherman so that they could record the sounds for their rc models.
ya i checked those out before on the tamiya web site...downloaded there little clips...impressive tank modeling for sure...and im sure there very spendy...but when they fired they recoiled and muzzle flashed..tank sounds were killer..it showed the tanks they got there sounds from..allways been impressed with tamiya on the most part..even there regular battleship models are top notch:)
