My Silvertone 1908 uses a chassis shared with several other models

This is a 3 band radio. I completely recapped it. Due to mouse chewing I had to rewind both the primary and secondary of the AM portion of the long Oscillator coil L3. This is the part of the Osc coil that goes to C8 600kc adjustable cap on the primary side (see schematic). I used 40ga wire and guessed the number of turns of primary an secondary as close as I could. Voltages on 6A7 tube seem OK although G1 is about -15V on all three bands. The two shortwave bands play fine but I can't get any stations on AM band.
I tuned set to about 600KC and put another radio near the set and swept through the AM band and I think I can hear the Osc. working around 1050kc on the second radio (more or less). Still, I can't get any AM stations no matter where I apply the AM signal using a signal generator.
I suspect it is my rewinding of the part of Osc coil that is at fault but I sure would appreciate any advice I could get.
Meanwhile I am searching for an L3 osc. coil off a parts chassis or a parts chassis for a Silvertone 1906, 1908,1904,1914,1954 or 1964 as they all share the same chassis.
