Post Versalog Slide Ruler with Case, Adjustable Set Square, And Roll-o-ruler. Lot. The slide ruler is like new no wear or scuffs. The case has a couple of minor scuffs. Looks like it was made around 1960. The adjustable square has a crack in acrylic as shown in the picture. The Rolling ruler is nothing special just came with it.
