I am thinking they are the 380 or 385 but not sure how to measure the difference. The balance measures 30" long. They are going in heavy single pane hurricane windows in FL.
Thank you for your help!

Hello Adam!
Thank you for reaching out to us. This appears to be either the Series 380 or Series 385. The difference between the two is the depth of the bottom fitting as shown below. Your stamp doesn't match any of our stamp options though. Can you weigh your window sash on a scale and tell us the precise weight?
