The outlet of the tee would be pipe size. Then a section of pipe with a hub would slip over the outlet of the tee and get caulked in with oakum and lead.
So the pipe often goes bad or cracks. So rather than removing the hub that was leaded in over the tee outlet they just cut the pipe off flush with the hub.
Then they didn’t have anything left to connect to other than slipping that reducing Fernco over the hub.
The pipe coming out of the top looks to be galvanized.
The inside of a 2” cast iron hub is about 3”. The outside is about 4”
The copper pictured is 1.5”. A red brass bushing is used to adapt the two and is caulked in with oakum/lead. The proper name would be a red brass caulking ferrule.
The work was probably done through a little hole cut under the sink or from the other side of the wall as a repair. Pure speculation.
