I have a reprint of the 1923 Meadows white flint granite grist mill instruction and parts manual. it is 24 pages. The manual covers the operation, trimming burrs and tramming the burrs to operate the grist mill. has all the parts and even how to oil the machine. also has a special section on the grits bolter. Yes all the info on how to make different sizes of grits with the extra grits bolter machine. alot of cool info. front and back are card stock and it is face stapled.  measures 8 1/2" by 11".
