Hi there Swisco,
Thank you for your help! I am looking for two window balances for a non-tilt window. The balances are about 33" long, and are 1/2 wide. They have the markings "32 5 LK CLADWELL" on each of them. The uploaded photos show both the top of the balance (with a plastic part that was in the window frame), and the bottom part with no other plastic parts. There appears to be a small block and tackle inside the balance, as well as spring. Thank you for your help! I am looking for four such balances: two to repair the window, and two more for the next time.
