Colleagues, my mind is collapsing! :)

Everyone knows that the launch of Intelsat-603 was partially failure. The satellite remained in the LEO without upper stage. The new upper stage was delivered by the rescue mission STS-49. The new upper stage was attached to the satellite, and then launched on GTO. In the GTO upper stage was separated and the satellite was transferred on GSO by own LAM.

Q: What catalog number or an international designation given to the new upper stage after separation on GTO?
This object is absent as in the official orbital information's site of the Space Command as in the logs of Jonathan McDowell. It's weird, is not it?  ???

An object transferred from STS-49 to the satellite would not normally be catalogued.  (This is the policy with ISS modules, for instance.)

It would normally be catalogued after separation from the satellite.  The fact that it wasn't suggests that it wasn't tracked.  Perhaps it decayed rapidly, perhaps high-apogee orbit was susceptible to perturbations that dropped perigee into atmosphere.

Thanks.

RAE Tables are give estimated orbit for this upper stage:
i = 28.3°, Hp = 345, Ha = 75120, AoP = 180°
May be the very high apogee of this object denied to detect and track of him.
