Finally took delivery of the guitar from Roger Williams - he has done a fine job of restoring and repairing the instrument.
An initial inspection convinced him that the piece had been well looked-after and didn't need refinishing. ("One of the best of this age I have seen"). The frets clearly needed work doing, as did a saddle replacement - the latter was a poor fit. The saddle block needed tapering to allow the action to be reduced. Here it is finished:
On closer inspection, however, it was clear that more work was necessary. Having attempted to level the frets, Roger found that the fingerboard, originally flat, had become concave, causing the fret ends to lift and making it impossible to level them properly. That meant that the fingerboard needed to be re-surfaced and then re-fretted. Also, the tuning machine rollers were badly cracked and were not far from disintegrating:
So new tuners were required too. Here are the replacements:

After replacing the frets and modifying the bridge, the head-stock sides were dressed and re-polished; and the neck - a little "lumpy" from nail-marks - was re-polished too. As the neck was being re-finished, Roger suggested the addition of 2 pearl position dots on the fingerboard edge. I opted for 1.5 mm ones at the 5th & 7th frets:
Finally, he re-strung the guitar with the strings shown above.
All in all, a lovely job, well-done and reasonably-priced. It's easy to see why Roger has the reputation he has for his work.
Any comments from forum members is most welcome.
And thank you again to those of you who pointed me in Roger's direction.
