I have a little more time than I originally thought, so I had a chance to look a little more.
There's quite a few recipes that use the container (76 according to the tradeskill_recipe_entries table):
SELECT DISTINCT(tradeskill_recipe_entries.recipe_id), tradeskill_recipe.name FROM tradeskill_recipe_entries LEFT JOIN tradeskill_recipe ON tradeskill_recipe_entries.recipe_id = tradeskill_recipe.id WHERE item_id = '17124' ORDER BY recipe_id ASC

So, it looks like recipe IDs 9145 through 9151 are the orc slayers. So I guess that answers my original question, and the combines look to be in the DB.
Looking at the Orc Slayer Greaves recipe (recipe ID 9149), it looks like the pattern is "Tattered Pant Pattern", which is item # 19560 in the PEQ DB:
