I tried to identify what I have is of series 395 or 385 before making an order. It's 16'' long, with 1540 # imprint on it. Thanks.

Hello,
Your balance looks more like our S390-16 with a 1-1/8" Depp bottom attachment and 1540 spring strength option. Take a look and please let us know if you have any other questions. Thank you!
