Nozh ERA equips T64B1M and BM Bulat, not older T64BV with Kontakt1 in the photo!
T84 is an old model so it's equipped with surplus Kontakt-5 blocks from its T80 Hull or indigenous production Nozh ERA but It makes no difference because Nozh ERA shape is similar to Kontakt-5 shape externally, you can compare the shape of the side turret blocks in the link below to any T72 w.Kontakt5 (BM model 1989 or T72B3 or T90A)

As you Can see, Nozh equips T64B1M
Duplet ERA that equips OplotM is a different Story: similar to Russian Relikt ERA

So let's make clarity:
The tanks in Jane's photo are T64BV with old gen kontakt1
T64B1M and T64BM Bulat and base T84 (read up) with Nozh ERA, similar in appereance to Kontakt-5 so they should have similar values
Oplot-M is equipped with Duplet ERA (Nozh-2) with performance close/same as Relikt ERA
