Can someone identify this gun/marker? Is it Nelson 007?

This gun was left after a party in my house and I don't know anything about it basically. Even if it works. I think it is some kind of a Nelson 007 because it looks like this only it has space for a small gas container in the handle. There is also a missing sticker on the other side that has left a trace "Power Line 1200". Can someone identify it?

Direct quote from an expert in the field

Looks like a MKII Nelspot, sold in the UK by a company called Hi-Tec as I recall, who went on to make the Python and Viper pumps. They were unique in the industry for making the body out of plastic with a brass lined plastic barrel, that style had stock metal Nelspot innards then the later versions even had some of the internals made of GRP. The pump is very distinctive and if you look closely the sight rail and body are all one piece, apart from the plastic bits is standard RF nelspot

Hows that?

Yeah, this sounds like it. It does have plastic body which I found a bit odd
