I would take a serious look at that 2nd IF transformer (37). I would bet it is faulty, since you are unable to peak its trimmer at 455 kc. Bear in mind also that the AVC filter network (37B, 37C & 37D) are inside the IF can.
Many different 1940 or 1941 Philco chassis will yield the IF can you need to replace it; just be sure the replacement can has the AVC filter network inside. I see 40-150/155/180/185/190 chassis on eBay frequently, as well as 1941 model 41-250/255/280/285/287/290/296 chassis.
Once replaced, realign your radio for a 455 KC IF.
Good luck.
