The 32 round drum magazine for the AA12 shotgun, how does it look? Pictures?

[Dr Heelhook]

I've googled, but I at least don't think I've ever seen a 32 drum mag for the AA12. I've seen pictures of the 20 round ones but never one containing 32. Are they a lot bigger than the 20 drums? Can anyone post pictures of both of the two variants maybe? Thanks
