The windows are non-tilt with 1/2" wide channels. The balance itself is 25" long. The marking on the the balance is "24CP".
There was another window next to this one with functional channel balances and sash guides so I took pictures of the top and bottom of a good balance, as well as the sash guide, attached below. Apologies for the fuzzy pic of the sash guide - I couldn't get a good angle or lighting in the room at the time.
Thanks in advance!
