Does anyone know what it is? Did it vary based on date of production? Mine is from Nov of 1915, serial number 809720.

Standard twist for. 32-40 and .32 Win. Spl. was 16", but if rebarreling or relining a somewhat faster twist, either 14" or 12" would work very well. German 8mm barrels are 250mm, a bit faster than 10".
