For mine, you would have to ask Lord Raven (Shane), it's his figure, but I believe Roll Bar with a custom head.

I just use a Steel Brigade figure as Stormer, since that was the codename I used back in the '80s when I "joined." I should have the Steel Brigade filecard info for Stormer up in the attic somewhere.

Before that, I'd actually joined the Action Force Club (done by Hasbro when they took over from Palitoy) and the codename they gave me was Night Hornet. I've assigned that identity to one of my Steel Brigade Paratrooper figures, so I can now have Stormer and Night Hornet working alongside each other and they're BOTH figures of "me!"

When I sent off for my Steel Brigade membership, I got all the personalised documents back but they sent me a (carded) Tiger Force Duke and a letter saying they'd run out of the Steel Brigade figures! So I didn't actually HAVE Stormer as part of my active Joe-verse until I finally got one on eBay in 2005!
