I just got my copy of Airgun Hobbyist today and it is a very good article on the Rutten line, far more extensive than in the blue book. Some of these must be exceedingly rare? I saw a copy on line of the Winstar Mach 1 manual and it referenced the 200 and 250 DE, but have never seen or heard of these? And as you said a break-barrel? And other Browning variations.
