Question regarding Sam Browne belts of the late 19th century

[elhombreconnonombre]

As I understand it Samuel Browne lost his left ARM in India during battle so he came up with the idea. His flapped holster was mounted on the waist belt on his right hip for drawing with his right hand. So I assume he used a cavalry draw to draw his revolver with the butt of his revolver facing rodarse the back. My question is which is the acceptable/correct mounting position of a flapped revolver holster using a Sam Browne belt. During the latter part of the 19th cent.

...rather he used his right hand to draw his revolver from his right hip using the cavalry twist draw since it was customary to wear the holster with the grip to the front.

I've seen british officers wearing the holster on either side, does not seem to matter, the determining factor seems to be if a sword Is worn.

[Sir Charles deMouton-Black]

I don't know the detailed history, but in WWI, artillery officers wore their revolver behind the right hip. I presume it was because they were either prone with their enormous binoculars in front of their eyes or peering down at a map or plotting table. I have one in my collection belonging to a C.E.F. officer serving in an artillery brigade.
