These are a couple glass installation tools. They were made by Chrysler/Boeing long before I was born. One is used to open the groove where the lock strip fits into the window seal. The other inserts the lock strip into the groove. The lock strip slides into the top of the tool and exits at the business end of it. You loop the strip through the wire end and insert the end of the strip in the groove of the seal.
Working from left to right, and using some soapy water, you push the tool along inside the groove and slide the lock strip in. The wire end of the tool spreads the groove open so the strip can fit in.
