IIRC
This rifle is featured on one of the 'Airguns in Action' AGW videos.
The guys concerned used to shoot at Man City ground too

( in the days before they bought their success

)
One of those men 'AJ' used to design and run the target layout for the AMTA - Airgun Manufacturers Trade Association at the Midland Game Fair for about 30 years .
He died some years ago
Also he was a fellow member of Failsworth Airgun Club (behind Manchester Airguns ) which used to shoot in a disused Mill that had a 70 yard indoor range.
Fond memories and he introduced me to Ripley Rifles .
