I’d say that was Venom blueing but to be honest it could be anyone’s who got a polishing mop and a blueing tank.
Impossible to tell what’s been done inside unless you strip it (takes two minutes) - could be anything from a PWR LOK spring and guide set to a full lazaglide tune, as Phil said, not all comp tubes were blued - none of the very early ones were. Always makes me smile to hear people saying ‘have you got paperwork to prove it’s a Venom?’ Venom/ac etc ceased trading nearly twenty years back and of all the Venom rifles I or my mates have got or had, two have had original receipts...
I’d have that back block screwed off right now and see if it’s got a fixed rear guide - if it has, smile.

Cheers, Craig
I and I am sure lots of others have fixed a lot of guides and compression tubes when reblacking guns
