The Character Options/Underground Toys release of the War Doctor's Sonic. The sonic used in the 50th anniversary episode was a modified 4th Doctor's CO toy sonic. They removed the bullet halo, added a round red button/dial/knob thingy on the bottom, and a red LED as the new emitter. So this toy replica is just about dead on. It's a nice link between the old style and the newer versions seen since the 9th Doctor made his return in 05. It also has become my favorite sonic.
