I don't have PF 98, but here are a couple of PB models from 1951 that look somewhat similar.
The 2204 uses the same type of bezel mount as the set in question, but has a pencil box on the front.
The 2301 looks similar and has the secondary controls mounted on the back, with no pencil box.
On both models the power xfmr appears to be sub-mounted, but in the same location as the 1949 model (the 2002).
Of course, both have larger screens than the 1949 model in question.
Check out the grille and feet!
