Spiral Window Balance

A contractor from New Orleans LA says:
I have a house that was built in 1948 I am looking to replace the attached parts on 20 original wood windows they all look the same but the tube is different lengths. The tube is 28 inches long on the attached pictures Can you help me identify?

This is an old one, but I believe you can use our Series 500 as a replacement option. You will also need a bracket like our 17-012. Let me know what you think!
