It is an OV-10 Mohawk. A US Army fixed wing observation plane that came into use during Vietnam and ended its service life in the mid-90s. I recall reading an article in the post newspaper while stationed at Ft. Hood. It was about the last of the Mohawk units deactivating.
I'm not sure about who makes that kit, but I know Roden has one of the latest releases of a Mohawk kit:
