The ICM kit has been called a clone of the TAmiya kit, and it may be. I have done several and they do build up into nice models. One word of caution though.......you need the serial number to see it it is a P-51D or a P-51K. The "D" had the cuffed , round tip Hamilton Standard prop. The "K" had the Aeroproducts prop. What you get into the kit is the cuffed prop, and post war "square tip" Hamilton Standard prop. Ask around as a lot of Tamiya and hasegawa kits come with the Aeroproducts prop.
Plus the "K" had the "Dallas" canopy. Again you need the serial number.
