On most sets I have worked on the tuning condensers with the smaller sized  plates in the oscillator section offer minimal means of adjustment, just a trimmer to set the high end of the dial. The ones with equal sized sections have either a slug tuned oscillator coil, and the small trimmer on the tuning condenser , or a larger adjustable cap called a "padder", most schematics call it a "600 padder" rather then an iron slug, as well as the small trimmer on the tuning condenser. I much prefer sets with the equal sized sections in the tuning condenser, it's much easier to get the tracking spot on, with the other type it's sometimes hit and miss. Getting back to the IF transformers was there a single peak or a double one when you were adjusting them?
