I found this in the garage. It seems to the unused. I find it particularly interesting because inside the box were these papers folded up.
The papers identify it as a Pressure Blasting Analyzer. There is also what appears to be receipt and a schematic type drawing. The signature on the first page does appears printed not by hand. Another thing I find interesting is that the numbers and other writing has been hand etched into the metal.
My grandfather was chemical engineer with the reserves . I know he was in hunstville, maryland, and germany. He was certainly in other places but I never heard anything about being in Houston.
I understand what it is and, I see they are still made and this company is still around. It says the patents has been applied for. Is this a early model? Who is EW Oakes? Were the papers included with every set?
Anyone have any good suggestions or facts to help me get started? I would like to know if it is worth money.
