I took this off one of similar vintage. Might have modified it some for the final stringing. String No. Note No. A (mm) B (mm) Speaking Length (mm) Diam. Wrap (in.) (inner/outer) Diam.

Serial 22715, (1914). This one has the right angle turn connecting the bass bridge to the treble bridge. I am doing a complete rebuild on this one for a client and it was restrung probably 50 years ago- incorrectly I might add. I have the "Guide To Restringing" book that should list the correct scale but I can't locate it and it would probably take me half a day of digging in order to find it.
