Maple Strongbox:
Its in Craftsman Essentials 15. Requires components made by Scholar (Iron Stud, Stroma Resin) and Outfitter (Iron Sheet). Last time I checked the broker on Blackburrow for these, there were only 8 for sale. Cheapest was 47s.
As far as Elm Strongboxes go, not really sure of prices. Maybe 10-15s depending on server.
