Hello!!
The measurements of the bass are as follows:
The neck is a Eb quite low at the heel, almost in the middle betwen D and Eb. From Nut to final neck 46,5 cm.
From Neck to feet 58,8 cm.
Neckstand now 25 mm, apears to be was corrected with a wedge that is almost the half of this....And not a very fine job.
String lenght 108,5 cm.
Bridge lenght ,top to bridge center 166 mm.
Distance of F-Holes 164 mm.
Back lenght 115,3 cm
When I brought it, it was very easy to play. I lower the saddle just to give more tension and fit a thick strings. The bass is still soft to play but I think now the sound has more fat, more orquestral sound. I´m not an expert but I always thought the bass can be a "powerfull cannon" with a correct fit.
Your Gilkes is very nice. The maple of the neck looks great!!
Later I´ll put some photos of my Poellmann bass. It has also nice woods.
I´m vey happy with it!!
Regards ,
Fernando.
