Andersen sash balance ID needed

A quick learner from Newark, Ohio says:
Andersen sash balance about 30 years old - markings say D34 7#27 3 85.

Also says 11600-17 on one side and 11600-3 on other side. Approx 2 7/8 by 6 1/4 plus flange.

Any help identifying replacement would be appreciated.

Based on your stamp of 7#27, I recommend our 24-737 as a replacement.
