To the best of my knowledge, the factory never made any left-handed stocks. I had the late Eddie Aubert build a custom for me in 1979 and we couldn't even get the factory to ship a semi-finished stock for a lefty. I've owned and shot several including models Record, C-300 SuperCombo and Premier Los Angeles.
Try Wenig to see if they have any for the Record Model.
If you need Z-Springs or other common parts, let me know. I still have a few of most parts left. If you need a parts schematic and other information about the line, let me know.
