This has been a topic of discussing, cussing, and general disagreement for some time now.
However
Based upon studying old Philco ads and the three Model 70 Service Bulletins (57, 57-A and 57-B), I have drawn the conclusion that, at least, the early model 70 cathedrals (without AVC) use a medium rosette for tuning and three small rosettes for volume, off-on and tone.
If memory serves, I believe most model 70 consoles used the same knobs as model 90 (large rosette for tuning, small rosette for off-on, medium rosette for volume and tone).
But I would have to re-research some of this to state solid conclusions (again)...and, frankly, I do not have time to do so right now.
