No one. I have one of two correct existing models. Fellow that made the masters could find anyone to take over and make the conversion kit. He built one on a Tamiya and sent me the only other set for the many photos and technical info I sent him from my time working with M-46s.,to get the parts made. My M-46 is set up exactly as my tank in Korea, down to the USA number on the sponson and is all El Mod. Check out U-tube M-46 Patton in Korea.
