Hi and welcome,
Generally there are two different version of the 84B chassis there's a code 121 and a code 122. The 122 was used only in the last of the production and uses octal tubes. The earlier 84B's use the older standard base tubes (this would account for just about all of them). As for the heaters being grounded or not I would look at the run number and circuit updates to get something that matches the chassis.
Cabinet looks to have some extra holes. The two on either side of the dial and the ones near the spkr have been added. The Philco spkr is real close to 8" but doesn't line up w/ an 8" spkr mounting.

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.
