B.B. Noyes & Co. Green River Swage Blocks:
From page 577 of the Carey Machinery & Supply Co. Baltimore, Maryland 1929 Catalog #10.
These were the typical industrial production blocks of the time and had the option of being machined (planed) flat.
The earlier Green River blocks were probably made by Wiley & Russel, then later by the Noyes Foundry Company, both of Greenfield, Massachusetts.
Noyes made a variety blacksmithing equipment including the Greenfield Caulking Vise and Noyes drill presses.
It is speculated that Noyes may have been a job shop and were doing the casting and some manufacturing for these other companies.
They definitely took over lines of tools previously made by others.
