It's a British C130 Mk 3. I use to work on them when I was stationed at RAF Lyneham. It has the cupola fitted to the front escape hatch. It has a fuselage plug behind flight station 245 and on at the rear at ramp station 0. It was designed to carry over sized loads. It still had the same weight capacity of the Mk1. The only error is the para door at the rear. The door was never moved. It should be behind the air deflector door. Not close to the ramp.
It is British because it has the stuck on refuel probe over the co-pilots window. I don’t know of any that have been sold to the civil market, so I can’t comment on the operator of this particular model.

Here's a link to the RAF web page on the aircraft.
