My sense is that old school chrome SLRs attract very little attention. An iPhone, M43 or schmaltzy p&s, DSLR--different story. Anything MF with a WLF--just a weirdo not worth the trouble. Probably something like any of the Nikon FM/FE variants would work. Nikkor lenses in your focal lengths aren't very pricey. Makes for a small, lightweight kit that delivers function and optical quality. I'd shy away from old, compact 35mm rangefinders in favor of SLRs.
