The Hub

I inherited a 70's D28 that is a players instrument. The action is too high for me, but the saddle is bottomed out. There is no obvious belly bulge. The top of the bridge has been shaved. Bridge pin holes are uneven in diameter. However, the bridge placement seems pretty close; within 1/32". A straight edge on the fret board sits about 1/8" below the top of the bridge. The fret board has plenty of finger worn wells, there is virtually no fret board radius, the head stock has been broken and repaired twice (the last one seems stable), and it could use a fret job. The neck itself seems straight. The relief measures at about 0.005". No obvious twists or warps. The heel is tight. I wonder if replacing the fret board / bridge / saddle would give this instrument new life. I suppose a neck reset should be considered as well, but the lack a radius and finger wear wells have me concerned. Thoughts? Recommendations? Referrals?
