Hardness Tester Testing 6" Flat Table 5 Test Blocks 2 1/4" Anvil Ball Indenter

Description

The Flat Anvil is 6 Inches Diameter, the "V" Shaped Anvil is 2 & 1/4 inches diameter.
I list the brand as "Federal Pneumo Centric" for the sole reason that other than the blocks/capsules this is the only name brand I can find - The Anvils might be Rockwell. I don't know for sure.
The Testing blocks read: (I'm interpreting the "Type" as the "letter" under the Diamond Logo which I believe is where the brand name is in either Japanese or Chinese)
91.7 HRB - Type B - (Number on the side of the Block - 0612837 )
82.1 HRA - Type G - (Number on the side of the Block - 07541 )
61.0 HRC - Type G - (Number on the side of the Block - C71C263 )
48.0 HRC - Type Z - (Number on the side of the Block - 067349 )
28.0 HRC - Type D - (Number on the side of the Block - C76199 )
Underneath what I believe is the "raised ball indenter" is the number "0994"
The capsules read "Rockwell Diamond Indenter - Type HR-1" & "Rockwell Diamond Steel Ball Indenter - Type HRB-1" Note only the one capsule has the indenter, I believe it is the steel ball indenter one with that bag of extra steel balls.
