SCARCE EARLY STEPHENS NO. 9 BOXWOOD & BRASS SLIDE RULE - 2FT 2 FOLD

Uncleaned as found. Imperial graduations. Missing inner alignment pins but complete with brass slide. Good overall condition noting a couple of nicks and some common edge wear. Few other examples of this rule exist online through my research.

**All edge tools may need to be sharpened/honed before use**
