Two of the three have since been identified; therefore, leaving Helios 2A (04049A / 28492) as the likely ID.

This corresponds to mean anomalies between 134 and 172 degrees, so 43 to 54 minutes early on your search TLE. With weather permitting I will try a more thorough planar search near the expected mean anomaly tonight.
