Trim the meat from the bones, and then cut it into small cubes. Brown it in a large skillet or in the bottom of a dutch oven. Add onions and mushrooms and sauté until onions are starting to toast. Add 6 cups water, bouillon cubes. Add mixed vegetables, ketchup and seasonings.
Bring to a boil, stirring occasionally; reduce heat and simmer for an hour, adding water as necessary to have enough stock. Add barley, simmer for another hour.
Hint: adding the barley about an hour before the finish keeps it from bedoming too mushy.
