Gang,

Both of my SW-3's have tube shields on the RF amplifier tube.  One has a 
National type TS, and the other is a type T58.  There is an aluminum 
mounting ring around the tube socket.  Either shield will fit either radio.

Picture of similar shields here:

Mine are 2.05 inches O.D.

Hope that helps a little,
Al
