The SSR lists these satellites as SL-8 R/B's:

 8874 76-051B  SL-8 R/B              CIS   104.8  83.0  1003   967   7.6
12150 81-006B  SL-8 R/B              CIS   104.7  65.8  1018   938   5.5

I searched through Russell Eberst's observation from 1980 to 1996 and found
no obs of 76-51B and only 5 obs of 81-6B.

The best observed (by Russell) SL-8 is 79-20B (Intercosmos 19 R), which
decayed from 495 x 988 km (1979 Mar 03) to 450 x 718 km (1996 Dec 31).
Without the "Grand Archive" it is very difficult to analyse his magnitude
estimates for 79-20B.

The only well observed (by Russell) SL-8 with a near circular orbit is
68-40B:

 3230 68-040B  SL-8 R/B              CIS    97.8  74.0   683   623   1.6
