https://imgur.com/a/KGkwfEPI'm trying to identify my old windows at home (~30 yrs old), as the jamb liners are all breaking down, and many of the windows need their spring balances adjusted or replaced (some sashes fall down a couple inches, some fly up a few inches when unlocking the windows).There aren't any brand identification marks that I can find, only the code on the inside edge of the window panes.I've linked to an album with the window code, and with a pic of the cracking / splintering jamb liner. via /r/DIY http://bit.ly/2KCyklv
