What kind of gun is this?

Hi Guys, I picked up this gun from an old property my father had owned. I was hopping someone could tell me what kind of gun this is, i have looked over the net but found nothing. There is no markings on the gun, its a .177 cal. and the barrel is NOT rifled. There is a screw near the trigger that adjusts the sensitivity of the trigger.

Looks a lot like a 1960's Relum Telly 822 though I always thought they were rifled. Relum were a Hungarian company. the underlever Tornado model was the most popular though I don't know why as they were all crap budget guns, suppose it was the kudos of having twin springs though you got better "performance" using a single BSA Meteor one.

I had one of those back in the day. It had some similarities but was a little different. I remember the double spring and steel but plate. It was a bit of a beast to cock with those two springs but made reasonable power compared to the other cheap puss piles that were around back then.
 
Looks nice, does look a bit like some Relum in a way, esp. the trigger adjustment.
Those star shaped lock nuts are going to give it up I think butb cant place them in my mind, more Hanell looking there but it's not a hannell.
Finger grooves look very home made to me, givin the age such work would have been A+ quality.

Maybe start with some Relum diagrams & strip it on down for us all to see,
