This is Torres' SE 99 I picked it at random fro Romanillos' book. I gave it the same analysis at I gave the 27 Santos, the width of top side to side at saddle, ect. and laid plantillas over it from half patterns I have from actual guitars, with the exception of Hauser. I took the Hauser from the Brune' 1937 drawing. Heres what happens, they all hit the points of three soundhole widths upper bout width at center of sound hole. They all hit the waist at the same precise point and they all are exactly 14" wide at the latitude of the saddle. Dead on. The makers are Hauser 1937 Barbero Mid 50's, Santos 1920 and 1927 - all line up with Torres SE 99 which is a typical mature guitar. Freiderich hits the mark at the saddle latitude at 14" dead on, but he goes wide in the upper bout, but still keeps the narrow point of the waist at the line under the soundhole. They all do as that is where that lower lateral brace is placed. 1986 Barba, misses. He is following late post 60's Ramirez. He only hits the narrow part of the waist at the lower edge of soundhole. But as I said they all pretty much hit that as the braces goes there and makers want that span to be the narrow point. But here's the thing, Barba back length is 1/2" longer than SE 99 so its stacked square rectangle is larger than SE 99 and the upper bouts fit more into that larger width square. So he misses the actual key points of SE 99 and Santos et al, but he is in keeping with his own proportion, more or less. Longer back, longer wider rectangle equals wider waist. But since sound hole radius is not a thing to mess with he stays with the conservative 3-3/8" ish standard sound hole. This means his upper bout width at mid soundhole is wide. It's frankly not attractive as the Santos', Barbero and Hauser plantillas that hit that dead on. Some more numbers- Santos 1927 - Upper bout 10 -1/8th or very close Waist 9- 3/8 ths Lower bout 14 at saddle and slightly wider at wide point 14-3/8 ths Which means Santos fairs out with a modern English inch into normal fractions, not crunchy weird metric random numbers. He laid it out with a ruler and rounded widths to nice fractions. I've seen the same in Ramirez III work laid out to the 16 th of an inch spot on. The reason he did I wager is so all the workmen in the shop will be on the same page.
