My bet for the original post, would be a post war Ford E93. It has all the hallmarks, transverse leaf springing, A frame axle locations, and Torque tube. Armstrong lever action dampers suggest post WW2. The brake drum/hub profile suggests Ford.
For many years, all vehicles with semi floating rear axles had the brake drum cast integral withte hub.
Removing a Drum/Hub from the taper on the half shaft required a powerful puller, and often heat.
I made up a puller for my Ford 100E rear drums from water pipe and a HEFTY forcing screw. That worked, cold, fortunately.
Fortunately, the later 105Es had drums which were separate from the hub.
Trying to remove the rear brake drums from a late vauxhall Wyvern initially resulted in my bending a shop made puller (1 x 1.5″ channel with 5/8 BSF forcing screw ). Straightening under a press, and a second piece of channel , back to back, failed, until a blowlamp was used.
Even then,,it did not come off immediately. Was giving up, when the heat soaked through to the hub, and it flew off, landing several feet away!
Judged by the condition of the chassis, “for spares” would be a good description.
