Murray,
Try your local toy shops for cheap plastic painted farmyard and/or coyboy figures. They're virtually 1:32 scale, weigh nought and are realistic looking to the extent that some can be used 'as is' . Others can be modified by the simple expedient of trimming off accouterments (who wants a gunslinger as a deckhand) or by amputating a limb/s and re-pinning in the desired position.
Fotos below (hopefully) should give you some idea of what can be achieved without undue hassle.
Good hunting.
