fingerboard 1.75 x 2.25 with a 12 in radius. Shape of carving varies depending on year and personal preferences.
Spacing is harder to answer, here's the long story:
scale length = 34
string dia. 1=.030 2=.050 3=.070 4=.090
at nut end:
fingerboard width = 1.75
treble edge allowance = .15
bass edge allowance = .15
string center 1 to 2 = 0.463333333333333
string center 2 to 3 = 0.463333333333333
string center 3 to 4 = 0.463333333333333
spacing between 1 and 2 = 0.423333333333333
spacing between 2 and 3 = 0.403333333333333
spacing between 3 and 4 = 0.383333333333333
at bridge end:
treble edge allowance = .15
bass edge allowance = .15
string center 1 to 2 = 0.67
string center 2 to 3 = 0.69
string center 3 to 4 = 0.71
spacing between 1 and 2 = .63
spacing between 2 and 3 = .63
spacing between 3 and 4 = .63
string edge to edge = 2.13
(projected) fingerboard width at bridge = 2.43
fingerboard width at nut = 1.75
fingerboard width at 24th fret = 2.26
Note that we calculate our spacing center to center at the nut and edge to edge at the bridge. You can't compare our .62 spacing to another maker who uses center to center bridge spacing. I inserted the typical string sizes we encounter for UK orders, so the spacing will change somewhat for larger strings.
Hope this helps!
