Thanks 'Local Boy', that's 'more better'.

It is a better focused photo than the one in 'Rcat's original post.

I was wrong about the carbines. The 'boxy looking' magazine-gates were my delusion.
The stock bolt-handle 'cut-out' shows them to be model 1896 carbines.

I didn't notice the double-action revolvers in the top of the gun racks, before.

At the left edge of the photo, a Cook (possibly 'Black'), is partially shown wearing an apron and holding a 'Dinner Tri-Angle'. He was apparently cropped out of the original posted picture.
