Vermont Castings vigilant II burning bit

I picked up a vigilant ii for $100 barely used. Replaced all gaskets on the doors and installed it in my guesthouse. Works very well with ohio lump / egg bit coal. I did not have the restrictor plate so I fabricated one. The shaker grates although not the best, seem to work just fine with this coal. Been playing with it for about a week to see how it does, no problem holding a fire overnight. Thought this might be iseful information if someone comes across one.
