I'm looking for the 31" balances and top sash guides that work together in this style window. On this smaller window where the parts were intact the balance was labeled 18 4 Caldwell DM.
I want both the balances and the top sash guides.

Thanks for your photos. Based on what I see here, you have either our S380-19 or S385-19, depending on the depth of the bottom shoe. That's the only difference between them. I recommend measuring your shoe and referring to our dimensions to confirm the best match.

For the top sash guide, see our 18-124P.
