I have installed the following web pages relating to North Bros.”Yankee” ratchet mechanism tools:
http://jp29.org/wwnbyankee.htm .......... North Bros.”Yankee” ratchet mechanism tools (overview)
(Actually the links to the other pages can be found on the http://jp29.org/wwnbyankee.htm page)
I would particularly like to determine the time frame when the 1530 ratchet hand drill was suprseded by the 1530A model.
