Hello everyone.  I have an odd plier type tool for the ADT Company I would like to ID.  When you squeeze the spring loaded handles it does two movements at the same time.  One movement is sideways.  Its made to compress a terminal or wire to hold it in place while the vertical movement sends a blunt point downward and pushes it into the top of whatever the tool is holding.  Has the numbers B2351  P-24408-P1 and  P-24406-P1 P-24407-P1 cast into the different parts of the tool.  Thanks in advance.

In case anyone is interested I found out what this tool was used for....

They are called Aero Tube Flanging Pliers and were used to flare tubing for an ADT fire detection system called the Aero System.  They formed a bell end on the tubing and were used with a compression nut to connect components of the system together.   Probably dates to around the WW2 era.

Hello, GarageMan. Thanks for letting us know!!!!  I never would have figured it out. Regards, Lou
