Jan, this is a specialistlc vehicle or as you wish a special-purpose one. The BAT-M is a speed bulldozer and the MDK-2M is a fraise trencher for digging trenches for tanks and other tracked vehicles. The film above shows the BAT-M/MDK-2M vehicle.
off topic guys so I apologise. but you guys know your stuff so I thought Id ask. Southern sky models here in Australia are advertising a 1/35 scale Centurion as used by the RAAC in Vietnam. Price is about $60 Au. Is that a reasonable price and quality do you think?
