Hi Dan,
That should work. If it is the primary, it is not tuned. If it is the secondary, you may have to add capacitance or crank down on the "trimmer" (a screw) on the section of the tuning capacitor that tunes that stage. If it does not "peak", you may have to add capacitance across the coil (just a few pF) or add the missing turn (it is OK to splice the turn in, I hear that just that Philco apparently did that on early sets when they ran out of wire in the middle of winding a coil.
Keep us posted. TRF sets are relatively easy, much easier than some of the early superhets with autodyne first detectors (oscillator / mixers).
