This listing is for two vintage metal rulers.  The first is from Fafnir Bearing Co.  in New Britain, Conn.  The will measure 6 inches, but is 6 13/16 inches long.   The back has decimal equivalents.  There are some discoloration spots on the back.  The second ruler is from L. S. Starrett Co., Athol, Mass.  It measures 6 inches long.  It is No 600.  No 4 Grad.  There is quite a bit of discoloration on the ruler, so it is hard to read.  They both come in a wood box.  The box measures about 7 3/8 inches long x about 2 1/4 inches wide x 1 inch deep. I do not think the are original for the box.  The box is missing one screw on a hinge.  It is also missing the velvet in the bottom of the box.  The clasp does work.  I will gladly combine shipping.  Please e-mail any questions.
