Looking for Kent-Moore tools #'s J-1693 and/or J-1693-A. There is a J-1693-B also. The Snap-On part is #AT-52 and the Kaiser is KF-77. New Britain also manufactured these tools under their own part number.
Also the rear band tool, Snap-On #AT-54 and K-M #J-5071
I have pictures of the tools available to help you identify what you have.

I need them to loan to my customers when they purchase HM rebuilding parts.

Post some pictures here-maybe someone might have them
