you have pictured, it seems to me the one used was a Western Digital

The most likely ISA ESDI would be the WD1007 controller.
There were a few variant submodels of that, such as with/without floppy

Mine had the ROM. On one machine, I had a 200M 3.5" drive. My first
drive of that size of both capacity and physical size.
I think that I know where it is.
