Hi Miriam,
So, did you get the brownish old finish off before you did the french polish? That looks a lot like what I thought was dirt on my 1938 Featherweight. I ended up stripping it off inadvertently, and am somewhat tempted to strip off the rest of it and then trying to polish it using Glenn's method. I thought I'd ask if you took the crud off or polished right over it.
