The schematic is a bit different. In order to tune the frequency and the coil adjustment, you use trimer capacitors. The new schematic is here (pdf, 88KB)
How to solder the coils and trimmers are like this.
There are many different appearances of the same functioning RFCs (inductors).
This component might be the most difficult to obtain depending the area (country).
