In 1959 Frank Miller published the first Pancake list containing only 29 padlocks. Then in 1978 Russell K. Soderquist carried the torch expanding on Frank’s vision. 2008 - 2016 the pancake list was built upon and maintained by David J. Heuermann, with special thanks to contributions by; Richard Bruno, Carl King, Jon Kolozvary, Mike Pitman, Bill Ryan, Don Stewart, Paul Vaverchak, and the multitude of collectors who contributed in making this Pancake list a success.

In order to make this Pancake list more complete your help is needed!
Please send additions/corrections/comments to: Michael T. Pitman. Please send pictures/scans of the obverse and reverse of the lock, and height/width/depth measurements.
