The last revolvers issued by Iowa State Patrol were S&W 686 ,this revolver shows being shipped in 1982. The Patrol was still using full flap cross draw holsters so their guns were well protected. ISP had S&W stamp their should patch/logo onto side plate.The troopers badge/ID number is on the other side of the revolver.I bought this , a blue model 13 and a model 66 from a trooper pilot who retired in 1992.
