Hi and welcome,
In the strictest sense it's not a trimmer but a slug. Trimmer infers that it's a capacitor. It's not uncommon on the secondary of the IF output transformer to be untuned. It turns up mostly in the later sets in the '50s. Probably cost cutting, not just Philco.
If it's got dual slugs the holes are hex so a plastic hex tool can be used to adjust both (one at a time). Your set has slotted slugs and the slots don't go all the way thru.

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.

Now I think I've got!
