The 113381 is a new number RCA used to replace several similar controls. It also replaces the vertical centering control when you remove the plastic shaft it comes with. The focus coil should turn maybe a dozen turns running the coils slug in and out. Check and be sure the slug is moving, I've had them detach from the shaft. Also make sure none of the wires have broken off the coils terminals because it does move around when the shaft is turned. If you have the socket unplugged from the CRT, check and see if you get any voltage on the focus pin on the CRT base.
