I found the article by Ross Siefried ( Giant Stoppers ) in Guns & Ammo- High Power Handguns
He touched on the Howdah in this story ,but it was more on 577 revolvers by Bland & Tranter
Also the revolver by Bowen in "577" that looked like giant model 10 S&W as you said on a Ruger Redhawk
that you cannot get with out a destructive device class 3 license .I was after a 577 Tranter here ,but when I tracked the owner down it had been stolen in a break in !
I sure would love a 577 revolver followed by 577 D/B Howdah !!

Thanks
