TLEs are available for this and other objects on these pages. Space-Track is no longer tracking this object. Actually, it's an odd case; they had TLEs up to 1969, then nothing until they briefly provided TLEs in mid-2017, then stopped again.

Click here for a graph of inclination and perigee height from launch in 1964 to a bit into the future. The inclination/perigee found at launch time are an excellent match to the catalogued values. Both because of this, and because the elements for mid-2017 match the Space-Track TLEs for that era, I'm confident of this identification.
