So we've been hunting for weeks for a loaner. We've looked at several good imitations built of plywood; these were all either too wide or both too wide and too high, and generally looked rather more like plywood than like cast iron. We've looked at several real stoves; these were all too recent, but even if they might pass for the right vintage, all weighed an absolute ton... being made of actual cast iron.
A wood stove of actual cast iron, but with beautiful roll-y wheels so we don't have to care how much it weighs - and sized to fit!
