I have not found a good source on these kinds of buttons. At Silcott,
Washington, we found the following brands of overall/glove buttons:
 
Can't Bust 'Em
Carhartt's O'Alls & Gloves
CSCo
Crown Brand
Days Big Five
Finck Detroit
Heet, Orr & Co.
Head Light
Oak Brand
Rip Proof
The Railroad
Underhill Brand
 
These are all illustrated in Adams, Gaw and Leonhardy (1975:263) and come
from an OCCUPATION context of 1900-1930.
