First, a micrometer setting fixture,1" to 6" I was told these were used at Mare Island Navy Yard so machinists could set their own mikes.
Second, a planer gage made by toolmaker Frank Way, back in the 1920s.
Third, a grinder's vise also by Way "It will grind as close as the machine can grind" Made in General Motors toolroom in the mid 20s.
Fourth, a tilting sine fixture, by Way; it can be held on centers, in a collet or on it's base, 3" c-c.
Fifth, an adjustable precision square, the blade pivots on the pin, and screws in the end of the beam project through to the blade for adjustment.
I bought some tools from Way back in the 1960s after he retired through an ad in the Machinist's Union Newspaper.
Sixth, a gear pitch gage; I think this was a Mare Island job.
Seventh, three unusual surface gages, the one at the right is Starrett, the others shopmade.
Eighth, a Shore Sclerescope hardness tester; it bounces a diamond tipped weight on the part being measured and measures the rebound; it measures hardness without leaving an unsightly mark as does a Rockwell hardness tester.
Ninth, a dial indicator tool for indicating in holes; the arm swivels in the center; a Mare Island tool, I made this one from a sample that I had.
Tenth, another indicator tool with swiveling contact point arm, can indicate a face, bore, or back face through about a 1 1/2" hole and 14" deep, also a Mare Island tool design that I made in my shop.
Eleventh, a similar bell crank indicator accessory by Brown & Sharpe.
Twelfth, all the indicator stuff in a box that I refit to hold it all.
