Moss Supply Series 1735 Size 3060 Balance identification

A home owner from Kevil, KY says:
Looking for Balance Channel for Moss Supply Series 1735 Size 3060. These are tilt-out Windows. Channel measures 34 x 5/8. There are no numbers on the metal channel. The insert at the bottom of the channel has PAT 4610108 and S(6) 679,000. Not sure of the first character, but suspect it's an "S".

Hello! Thanks for reaching out to us. I'm pretty sure we can help with this. I would start with our Series 795 channel balance. I don't recognize the stamps you listed, and they don't correspond to any particular size or spring strength in our catalog, so I would highly recommend measuring your metal channel to determine the length and weighing your sash on a scale to determine the proper option.
