When I was in school, I inherited my Dad's 280 gal oil drum rotisserie smoker (just pour burning coals in the base, and be ready to put out the flames with a garden hose all damned day), and we used to get really cheap sub-market weight pigs from the local producers with anatomic anomalies (hernias, prolapsed rectums etc.) that precluded automated slaughter, but didn't affect the quality of the meat. There was a butcher in Sidney, Il that would kill, scald, scrape, and hang the pig for like $7.00 We cooked the heck out of those guys (usually about 100-150# dressed) and, as I recall, the hams pulled and ate just as well as the shoulders. I imagine it probably had something to do with cooking them skin on, but honestly, the only thing we even really used a knife for when serving them was to open up the insides of the legs and cut the head off, and then to cut the loins up (which just lifted out whole by hand) into little steaks for the people that had a problem with graphically dismembered pig being shredded by hand in front of them. I don't see bone-in, skin-on raw hams commonly, but I bet they would smoke pretty well too.
