I just looked at the schematic in Riders 18. It's interesting that the FM IF frequency is 4.3 MHZ, like the pre-war FM sets. The coverage on your set is 88-108 MHZ. The schematic shows a 12AT7 as a 1st and 2nd converter.
Your pictures show where some of the caps were changed, but not all, including the 'lytics.
