Anyone know what Tobias neck width is @ 1st fret??

I asked Mike Tobias this question.
Here's his reply.

I don’t know what Gibson is doing. In the old days the nut on a 5 was 1.75 the last fret 2.75 radius was about 16”

A 4 string was 1 5/8 at the nut, and 2 3/8 at the last fret

6 string was 1 7/8 at the nut and 3 ¼ at the last fret.

I think that the same dimensions still apply.
