I definitely hear you on that one, John (even though I never tried 777 or anything of the same ilk), but what I meant is more that I have the feeling that the OP is badly processing his film, then comparing it with vintage prints that definitely have a lower contrast, better midtones, etc.
So I'm pointing him to the first step towards that direction, i.e. : controlling exposure and development so that at least he gets decent midtones. After that, the next step is to evaluate whether that is enough, and if not then the OP may well go deeper into vintage madness by using older lenses, films, developers, papers, and so forth.
My hunch was simply that properly developed modern film, even in modern developer, using modern lenses, would be a step in the right direction that could satisfy at least some of the needs of the OP.
