Can anyone help me identify these 1972 year spheres. Model: 11D430, 25 liters each. Metal is none magnetic not rusting.

Seems top and bottom been covered in some kind of casing.

What I have been able to find so far is:

Melnikov N2O4/UDMH rocket engine. Main engine of the Yantar-2K spy satellite orbital propulsion system. In production. The orbital maneuvering system of the Yantar-2K consisted of one 11D430, four 11D431, four 11D446, and eight 11D428. Up to 50 ignitions. Chamber Pressure: 9.00 bar.

Possible from Russian space program but I need professional opinion. Thanks.
