Qucik Time Stove

I HAVE READ ALL VERY INFORMATIVE STORIES HERE AND NOW I HAVE JOINED.
10 YEARS AGO I ACQUIRED (GOOD STORY HERE), A QUICK TIME WOOD / COAL STOVE.
YES I HAVE LOTS OF PICTURES.
IT SITS IN MY OFFICE AS A PIECE OF ART, THAT GIVES ME JOY TO LOOK AT IT.
NOW IT IS GOING TO BE PRESSED INTO SERVICE. MY PAST COAL STOVES WERE FEW AND VARIED.
AND OLD HAND FED ENGLISH RECTANGLE WITH A SLOTTED GLASS DOOR.
AN ALASKA CHANNING I COULD USE HELP TO REPAIR ( LEFT IT MY DAMP BASEMENT AND IT RUSTED TOGETHER IN A FEW MONTHS).
A READING WITH THE COAL TROL THERMOSTAT - SET IT AND FORGET IT, MADE ME A BIT LAZY.
NOW I AM PLAYING WITH THE IDEA OF A D.S. 160,000BTU FOR MY BASEMENT AD THIS ARTWORK QUICKTIME IN THE LIVING ROOM. LOG HOME HAS 26' CATHEDRALS 1+1/2 STORIES AND BASEMENT.
THIS QUICK TIME WAS IN OPERATION BEFORE I BOUGHT IT.
HERE IS WHERE I NEED A LITTLE HELP.
1 - THERE ARE NO GASKETS AT ALL?
2 - WHAT SIZE COAL SHOULD I USE? NUT?
3 - THE FIREPOT IS CAST THERE IS NO BRICK OR MORTAR LINING.?
4 - IT HAS A SILVER OR FLAT NICKEL FINISH. CAN I REPAINT, OR JUST STEEL WOOL IT?
A LIL RUST HAS STARTED.
5 - HOW LARGE A WOOD FIRE CAN THIS TOLERATE? I WANT TO USE IT MAINLY WITH COAL.
6 - ANY IDEA OF THE BTU'S?
DIMENSIONS:
1 - FIREPOT 17" WIDE & 8" DEEP
2 - STOVE HEIGHT 48" TO TOP OF STOVE ORNAMENT 12" +/-.
3 - MARKINGS
- 1" LETTERS QUICK TIME ABOVE THE MAIN DOOR HAS THE MICA WINDOW
- 819 BELOW
- 1920 ON ASH DOOR
- 4 SHAKER BARS WITH 2 EXTERNAL KNOBS TO ATTACH SHAKER HANDLE

Hello youre stove must be a more recent edition than mine.I would use nut for slower burning or stove coal for faster burning .There are no gaskets on mine ,the doors should make a tight fit, if they don't try adjusting the closure knobs.You may have to strike the ends of the latches with a hammer to bend them to tighten them.Be careful not to break them off.Do you have a magazine to hold coal on your stove?(A round pipe in middle of stove into firebox)I just finished my 2nd Quick Time in the fall.Does your stove say Swinton and co. on it?
