Vintage Starrett No.11   6 inch Combination Square Tool with Original Box - image 1 of 8

This is an old Starrett #11 tool for machinists, tool makers and pattern makers. It is labeled as a 6” combination square with center head with a hardened blade. The square head and the center head are stippled castings with the black Japanned paint finish and they both have a knurled lock. The square head has what is called a spirit bubble level and it has the original scribe inserted in the top. The 6” blade has the 4R graduation; 8th, 16th 32nd and 64th increments with 1/8”, 1/16”, 1/32” & 1/64” markings on alternating sides. The un-grooved side of the blade is marked with; No.4 Grad. - The L.S.Starrett Co. - Athol Mass. U.S.A. - Hardened. I believe this is from the early 1900’s. It comes with the original box which has a label that identifies it.

As stated, the blade measures 6” long by about ¾”. It is in very good condition minimal signs of having been used. There is minimal discoloration to the steel blade. The level bubble is intact and functioning. The box measures about 4” by 6 ½” by 1” and it is in good condition with minor edge and corner wear and light soiling.
