Does anybody know FOR SURE when the Remington 700 was first offered in left handed? I have a 1973 Shooters Bible, and it does not show a LH version of the 700. It does show a lefty 788, which makes me think it would have shown or mentioned the LH 700 had one been available. It is listed in the 1974, however. Does anybody have anything more definitive than that?

Thanks.
