On the end label, real Ivory was labeled "Ivory", Tru Ivory as "Tru Ivory", and USFA's own synthetic was called "US Ivory". The US Ivory came in 2 colors - a solid cream and a yellow. Didn't do much yellow. The initial JW Red River guns came with Tru Ivory but changed shortly thereafter to US Ivory. Speaking of grips, you can't imagine the number of calls that came in from dealers/customers looking for the wood grips on their Rodeo II. USFA called these brown grips "Burlwood".
