Paul Hailperin's Measurement Bell Joint Bore Extended Data and Calculations

This is bell joint bore data from Paul Hailperin's measurement of the Naust Hautboy, collection: Bruce Haynes
with extra data derived from calculations for bore ellipses and extimates of original bore geometry.

 Note:  [value]  indicates derived/calculated information.
   An empty shaded cell indicates that, since the measured lengths are the same,
    the values that would appear are redundant.
 1 [value]  indicates the row is for Socket. The length value at the top
     of the socket has been taken from socket tenon page (see Socket and Tenon data)
     The reference has been changed, however, from "Top" to "Bottom"
 n/a  indicates data not applicable
