Why are the connections offset on these inductor symbols? (see schematic)?

In the middle of the schematic, there are 2 inductors (the taps are connected to the emitters of the 2 NPN transistors)

Why are the connections shown at the 3/4th point, instead of in the middle?

    Those are inductors with a tap, or autotransformers. That allows the resonant circuit to be impedance matched to the low resistance transistor EB junction.

    why do you think they should be in the middle?

    I guess to show it isn't a center tapped tapped inductor. Center tapped transformers are quite common and would be shown tapped in the middle.

    If the tap was shown in the middle, most would assume the inductor is *center* tapped. In this case, the tap is closer to one end than the other, and the offset tap point shown on the schematic indicate this.
