Pickett N1010-MF, Rare, Silver Pickett 10 Inch Rule, in Case
A very rare, Pickett N1010-MF (metal finish?), 10 inch rule, in case. Scales: K, A [B, ST, T, S, C] D, DI, and, on the other side, DF [CF, CIF, CI, C] D, DI, L. This is the only 10 inch Pickett rule I have ever seen with the silver metal finish. The apparent white spots on the pictures are just light reflections from the silver surface; they are not really present. Excellent condition.
