Thanks for reaching out! This window balance reminds me of either the S351-30 or the S390-30. To determine which of these is the correct series, you'll need to confirm the depth (front to back measurement) of the bottom shoe.

The 2950 Stamp should be the same. A pair of these will support a sash weighing 28 to 32lbs.

Comparison of the S351 and S390 balance shoes.
