I am not associated with this ebay auction in any way, shape, or form. That said, someone is selling replica Legion flight rings on ebay if you're interested.
This isn't the original gold-plated DC Direct version but a homemade version that, from the ad, is available in all sizes from 4-15 (US). Cost is $55 ($40 for the ring, $15 for shipping from Israel).
If you do get one, let me know how it works out!
