Jaguar Rear hydraulic Hub puller for Mk1 & 2 solid or disc (US term as they all have brake discs) wheels fitted to live axles, not as shown in photo which was 10 or more years ago, now with a hydraulic ram.

Does the job / is the equivalent of Churchill JD 1 which is shown in the picture,  this in one of only hub pullers that can remove the rear Jaguar 5 stud hubs, approx 12 ton capacity

They also fit independent axle hubs as sometimes they can be difficult to remove, Jaguar from E Type to XK8 or later

These pullers come with a specially designed cap that stops damage to the end of the halfshaft, complete with full instructions & safety advice

A Workshop tool, not terribly expensive for what it is.

Sold as far afield as Australia
