Chuck, I'm still unsure. The graph points to rosette knobs yet the model 70 at the top of the page appears to have plain knobs. The working model 70 I have seems to have the same knob configuration as the model 90 at the top of your page. The parts 70 I have, has all plain knobs, with of course the exception of the tuning knob. So, still not quite sure on this issue. Can you shed more light. Am I reading your graph correctly? By "Rosette" in the knobs column, do you mean all of the knobs, just the tuning not, or?
