Warwick s/n lookup says this is product number: 1275080004BWBPOWWW, which is a product number still being used today. IF those specs have not changed for this product since 2016 (SOME specs have though, e.g. Ratio tuners, brushed metal pickup covers,... why does Warwick use the same product number ) then it has the following:
Fingerboard Radius: 26" (660 mm)
Scale length: 34" (864 mm) Long Scale
Width Nut: 45,0 mm / 1.8"
Width 12th fret: 60,8 mm / 2.4"
Width 24th fret: 69,11 mm / 2.7"
I can't get more quantitative than that at the moment, as I'm traveling. Neck feels pretty comfortable to me, so I don't believe it is a 'broadneck' Thumb, if that is what you're wondering.
'Broadneck' NT5 (product number: 1975671004BWABPFBW) has the following specs:
Fingerboard Radius: 47" (1200 mm)
Scale length: 34" (864 mm) Long Scale
Width Nut: 47,0 mm / 1.9"
Width 12th fret: 71,5 mm / 2.8"
Width 24th fret: 84,38 mm / 3.3"
