Baker Pat. date
I'm guessing this was made by Bonney.
No identification marks as can be seen or known by me.
Patent date matches one to a J.G. Baker who along with
friends reads as a who's who of Phila. tool history.
First pass at search http://datamp.org/ shows no images and none known to be produced.
Second pass at search brought up USPO with a revision and 2 pictures
Still no model #
These #s are on the anvil
