Default Question for Hallicrafters SX-28A Experts

I'm restoring an SX-28A that has been extensively hacked, especially
in the oscillator section.

The schematic shows a coil with one side attached to grids 2 & 3 and
the plate of the 6SA7 oscillator tube, and the other side going
through R47 (etc.) to the RF amp 6AB7.

I found R47 and associated components, but not the coil. Where is it
supposed to be?

Oscillator coil #1 is shown on the schematic to be center-tapped like
coils 2 thru 6, but my #1 coil does not have a center tap. The coil
looks original -- is the schematic perhaps wrong? The #1 coil does
nave a small 1-turn "secondary" wound over it: how should this be
connected?

I'd appreciate any help to get this old Soldier operating again.
