The top one is made of aluminum and bears the names of BRINSON MFGRS. SALES CO. and LEYSE ALUMINUM CO. Its backside is a table of decimal equivalents to fractional measurements, additional info commonly found on the back of pocket rulers used by machinists, engineers, and those in similar vocations.
The lower two are plastic and advertise Smith-Corona MARCHANT CALCULATORS. One of the front edges of each is ruled in typeface divisions, (I guess?) 10 to 64 per inch, their backsides are calendars for 1956 (red) and 1960 (gold, 50th anniversary).
