Am certain that whatever it is, or left the factory as, it is not a Myford ML4.
It has already been butchered, so getting it useable might be lengthy, difficult, if not impossible.
Parts may not be interchangeable with a lathe of a different make.
Trying to update to make a hybrid with parts from another different, machine may need a lot of work, if possible.
The changewheels for a Myford ML1,2,3 or 4 are not directly interchangeable with those for a 7 Series machine, or vice versa.
Remember USA vintage lathes may be dimensionally similar, but details like studs for the changewheel could differ in a variety of ways, and the changewheels could also, DP, pressure angle, let alone other dimensions.
A USA machine might well use Unified threads, rather than BSW and BSF of a UK machine, even if some of the fixings will apparently match (Unified will go into BSW or BSF in some, but not all sizes)
And with the advent of Chinese lathes under different importers and colour schemes, parts may not be directly interchangeable (There are at least three different marques of mini lathes imported into UK, not to mention into Europe and the Antipodes). Changewheels are Module, not DP, and threads will be Metric
FWIW, find another machine within you budget and space parameters.
