Vickers, Lewis, & Mountain Guns
These are WWI short range guns, I think all of them meant to be relatively light and portable so they could be transported and used in mountains.
would appreciate any information from anyone who knows about their operations, especially what they are especially good for and what problems can arise.
The Vickers was used, for example, by T.E. Laurence against the Turks when the Ottoman Empire and the Brits were fighting in the Middle East.

The Vickers was a fairly heavy weapon that was better suited to defence where as the Lewis Gun was a bit lighter and was used both on the ground and mounted to British aircraft.
The Vicker's was water cooled which can present problems if the water boiled off where as the Lewis was air cooled.
The Vickers MG's were the British main defence gun in the trenches that had a range of around 3700yds approximately firing a .303 bullet. Used in defence with interlocking fields of fire they were absolutely deadly. Here's some info on the Mk.1 Vickers.

both the Lewis and Vickers guns you refer to are machine guns that would be called light arms.
I was hoping to research more light artillery, i.e., a small cannon.
It appears the name Vickers was also applied to a light cannon used by the British in their colonies:
"The QF 2.95 inch mountain gun was the designation given by the British to a Vickers 75mm calibre gun."
I knew a Class III legal owner that had a Vickers water cooled, tripod mounted MG . I visited there once when some Police Officers were there firing it. They were pretty heavy thumbed and to my notion wasted a lot of expensive .303 ammo. When asked if I wanted to fire the gun, I did but remembered my Marine Corps training regarding MGs and attempted to fire single shots and after two or three attempts was able to do so. But most tries were two to four rounds fired.
We were taught that the enemy will put a mortor round where they see muzzle flashes or see aMG so keep the firing that they do not discover the location of the gun. And by the way, the cartridges were in a fabric type belt, not metal links as in American Browning MGs.
As others have said the Vickers would be quite a chore to hump up and down mountains as they are quite heavy. I estimate my Vickers with tripod about 80 lbs. The Lewis on the other hand is much lighter I estimate mine in the 20 lbs range. It wold be much easier to carry in rough terrain. There are plenty of parts still available for the Vickers.The Lewis not so much.
