Bob West of Eugene Oregon used to do left hand conversions. Some years ago one of his conversions was featured in Rifle Magazine. Although he started with an early true left hand action, he built a .375 H&H model 70 for me.

"No free man shall ever be debarred the use of arms. The strongest reason for the people to retain the right to keep and bear arms is, as a last resort, to protect themselves against tyranny in government." Thomas Jefferson, 1776
