André,
I am not aware of a specified torque for wheel nuts. Original brass Slough nuts were notorious for the threads stripping. If you have those I would recommend checking the threads carefully.
Last week we bought another lot of secondhand spares amongst which is an original jack.
It is a stubby, three-stage, bottle jack. Two stages are operated by the handle with an additional third stage which is screwed out manually to suit the jacking point height before placing the jack in position and then using the handle.
