Don't have any pictures, don't have a digital camera.
But, I do have an M27-2 with the 8-3/8" pipe. Gorgeous gun, but I'm thinking of selling it.
I used to have an M57 with the 8-3/8". Sold it some 15 years ago. Sorta' regret its passing, but it was killing my hands to shoot it much. I didn't reload at the time and the only ammo available was .41Mag full power loads.
I did sell an M29 with a 6" barrel. Couldn't stand the .44Mag loads anymore, same problem as the .41Mag, and thought I'd just replace it with a .44Spl model. Didn't do that, however.
