I thought both of them have big rosette for tuning, two small rosettes for tone and volume and small conical for power switch.

Now, my 70 came with 3 small conicals (Philco knobs) for all other than the tuning (proper big rosette).

I also saw images online with the same arrangement.

And, to finalize, that poor Philco 70 which I found for Brenda also has 3 small cone-shaped knobs. (link below)
I honestly don't think someone replaced them as part of restoration effort with this one.

So, were there different arrangements?
