Hello there!
Your balance looks like it could be a match for our Series 395. This comes attached with the 19-005 winged top and 15-001 non-winged bottom so I recommend looking this part over to confirm it matches up to your original balance. Since there's no stamps on your balance, you'll need to weigh your sash and refer to the chart under the product description on the Series 395 store page to determine the appropriate spring strength option for your balance.
We're glad you found us too! It's always a pleasure to help. Good luck with your repair and please let me know if I can be of further assistance!
