I did notice the finish under the bridge. And yes on the blades. I've ordered the one sided ones. They are also shorter. The longer blades showed me the top is not flat.
There is some bowing on the top. At the narrowest area of the body the top dips down towards the sound hole and the edges are high. In fact there appears to be some "banana effect", ie the neck working it's way up under tension. Also noticed that the free setup at Martin where the action was brought down ended up being the saddle lowered to where the string is barely clearing the bridge and the truss rod tightened to where there's a visible curve down to the head along the neck. IOW, it's twisted and needs a neck reset for any further lowering of the action.
This is bad news on the one hand, on the other hand it makes me feel less worried about refinishing a Martin. Maybe I'll end up resetting the neck myself and the guitar will serve as my learning project, which is a noble cause.
We shall see.......
