Bowen Designs aren't the only company that produce Captain Britain related busts, or statues. Diamond Select Toys have a few, not many, but there is a couple out there.
Captain Britain 80's bust
It's not a bad bust, but I wish it had arms...
The only other connected bust is one of Shadowcat in her blue costume she wore whilst a member of Excalibur, and I really like this one, especially Lockheed.
The only statue they do that has a connection to Captain Britain is... surprise, surprise... Psylocke, in fact there's two of them, one in costume, and in swim-wear.
Wouldn't it be nice if someone actually did a Betsy Braddock statue!
