Oh yeah, I'll share one tip about Carcanos that I learned when I was checking out a used one...
Do NOT disassemble the cartridge elevator assembly! The spring is supposedly very difficult to reinstall properly without a special tool that was presumably available to Italian Army armorers until 1943 but has been very hard to find since then.
If the elevator does not smartly spring back up after being pushed down, the spring is mangled or missing... and the rifle will most likely only function as a single-shot.
