Slide rule cursor misaligned, how did happen?

The C and D scales are aligned with each other, but the CF and DF scales are not aligned with each other. You'll need to loosen the screws that brace the two long stationary pieces of wood, and align those pieces. When they're perfect, then see if the cursor is still needing alignment, using the two outer scales and seeing if, for example, the .5 on the LL02 (top) scale lines up with the 2 on the LL2 (bottom) scale, and adjusting the cursor if they don't.
