The full name of the cartridge is the .270 Winchester Center Fire. WCF. To distinguish it from any other .270 cartridge, such as Weatherby, Holland & Holland, etc.
Yup
Yes, the Deluxe Model
i just bought a used one for 399.99 .it looks and shoots like a new one.

Not unless the Smith is chambered in caliber .270 Weatherby- and I have never seen one that was.
Yes
.308, and its derivative cartridges (like .243 and 7mm-08) and generally short actions. 30-06 at its derivatives (like 270, 25-06) are long actions.
It can only safely accept the 270 Weatherby Magnum if that is what it is chambered for. If you want to chamber it in some other caliber than get a new rifle. Just because two bullets have the same diameter bullet (270 or any other caliber) does not make it safe to fire it in your gun.
