To try to duplicate a circuit, normally one would need to know the coil dimensions, and in the case of a slug tuned coil such as this, the characteristics of the tuning slug. Without this information, you will have a lot of trial and error to reach the frequencies you desire.
I don't know what "VDR" on L3/L4 and the pickup link stands for, but could mean 5 turns and 1 turn. At any rate, the pickup link should be on the same coil form, and should NOT be electrically connected to L3/L4. If it were connected to the end of L4, the RF voltage at that point would be in series with the voltage magnetically coupled into the pickup link, as well as changing the symmetry of the oscillator circuit.
