Umarex/Air Hawk Elite II

I would like to have a parts list/diagram for the Ruger Air Hawk Elite II rifle. I don't seem to be having much luck in finding one. I have called Umarex, they weren't much help. They don't sell parts and couldn't/wouldn't tell me what I needed to know. At this moment I just need the size and pitch of the three stock screws. Any help would be appreciated.

Thanks,
Dave
 
You'll need to verify for sure. If you skip whatever the Elite II means isn't a ruger airhawk the RWS34 clone? If so the Xisico X25 should be the same (darn labels & relabels & ) . Were that the case Mike a flyingdragonairrifles is who I would try. Actually where I live I would carry the action into Ace Hardware and start matching things up.
Good luck on finding a PDF. Do keep us posted.
