I have three with one offset and one genuine Mangels brand with a different offset

Does any one have any odd 8 spokes with a Rover stud pattern? If so please measure your offset and hopefully it will match either of the ones I have.
Best case is another mangels so I have two with 1 offset and two with the other. Then I can run the big offsets on the front for more steering lock and the smallers on the rear.

Edit - Still need a rim.........
