I just looked at a sequence of Olaf the Violin Maker videos on a restoration of a Hill antique violin. Although unmentioned by Olaf, the violin had a very unique peg spacing in that it appeared that each side of the peg box was equally spaced for 3 pegs, with the middle peg space on each side unused. I could not extract a useful photo from any of the YouTube videos, but did find something as an example (although not as pronounced as the French made Hill).
The only reason that I can make for doing this is ease of hand positioning for tuning. Finding the peg hole for the a string must be difficult because of interference from the scroll.

Ahaaa! How curious.... yeah, indeed...
No doubt there is a rationale behind the peg spacing on the box....
But then again, I'm just a fiddler, so who knows ?
As I say, curious ( and interesting! - or - was it just a mistake ??? Trust me, I don't know !!! )
***EDIT*** -was there perhaps an intent for a 5-string version? LOL
I seriously recommend not copying my mistakes. D'oh -
Please make your own, different mistakes, and help us all learn :-)
