Please identify channel balance

I bought a property where one of the windows had a broken channel balance. The hook and string is completely missing. I intend on replacing the channel balance on both sides of the window. Included are pictures. I measured the width to be 1/2" the length of the metal portion is 20 inches. It has winged top and bottom and the bottom fitting has a depth of 1-1/16" depth. It appears both in color and by closest measured depth to be the 15-005. This leads me to believe that I need to order the 20" series 380 channel balance and judging by the markings on the side which read "19 4 GK Caldwell" I believe I should buy the 1940 option. Is this correct? Do you need any other information to identify this?

Hi there!
With this combination of attachments, you could have either an S380 or S385 channel balance. You’ll need to measure as shown below. The Series 380 has a 1" bottom attachment, and the Series 385 has a 1-3/32" attachment. You'll also need a spring strength option of 1940.
If you have any other questions just let us know.
