A bit unusual for a two-piece back to be 'flipped', rather than 'booked'. Perhaps not from a billet? The camera lens is a few degrees out, both x and y, tending to make the disparity in the C bout sizes a bit more in reality.
Good catch on the camera lens being a few degrees out. Sorry about that.
Thanks everyone for the comments so far. I am not the maker, I'm just trying to develop my eye(s).
I've seen two-piece backs flipped on I think an Amati and a Grancino. And, there was a thread quite a while ago where Michael D. said that doing this mades the back more stable - if I remember correctly. The sense I got out of that thread was that flipping one half was a personal preference of the maker on that particular day. Out of curiousity, how do you all feel about doing this wit h your own violins?
The neck looking unfinished is also a problem with the photography. In real life, it doesn't look this white.
In my opinion carving a really good bridge is one of the more difficult things to do. Requiring as much skill as building an instrument and often is the most demanding of knife and hand skills as well as acoustical knowledge.
Thanks to all who replied and also my apologies for responding so slowly. What was said gave me a lot to think about. I did buy one of the violins and after a bit of playing in, a new set of strings and a different bow, the extraneous sounds are much much less. I find that these extraneous sounds make the violin, as a tool, much harder to work with.
