Hi Mikael,
not sure whether you have found anything yet, but Simmons Wheels in Australia make pretty good 3 piece custom wheels to any spec/offset you require. Not sure how easily they could be sent over, but if you need assistance I'd be happy to help. This one looks a bit closed like the one you had identified. They have been used in racing and on Australian muscle cars for many years. They have a range of styles and a lot of sizes.
