The model 75 is one of the few classic match rifles that was made in a TRUE lefty version - not just the stock but the whole action, with the cocking lever on the left side. They are rather rare of course.
The photo above is a left-handed model 75 Universal (the true Running Boar model 75 looks very similar but has a longer scope rail, a single-stage trigger, and some other minor differences).
The old Anschutz 220 was also made in a true southpaw version. Other classic 10-meter sidelever guns (FWB 300, Anschutz 250) came with lefty stocks, but kept the lever on the right. The old barrel-cocking target guns (HW 55, Walther 55 and LGV, etc.) were also offered with lefty stocks to go with their inherently ambidextrous actions.
