Summit Coal Stove Circa 1910?

I am getting ready to use for the first time a "Summit" hand fired coal stove
that could be almost 100 years old. My previous coal burning has been with a
simple pot belly stove, but this Summit was clearly designed and made when
coal was king and has many features unique to the era. The large firebox is
housed in ornate heavy iron grill-work on the front and top, with heavy gage
sheet metal sides and back. It has a large swinging ornate loading door with
isenglass windows. It looks more like a piece of furniture than a stove.
The big feature (at least to me) is that at the bottom
of the firebox instead of a grate there are three very heavy duty ash "grinders"
that are turned with a separate handle, the ashes falling down into a large
tray for removal. When the grinders are stationary they act as a grate for
the bed of coal. This to me will beat the heck out of shaking.
Two questions - 1) anybody have one of these or know when it was made?
2) stove coal, or nut coal?

Many Thanks!

Sounds like a beauty. Pictures! Pictures! They will not only entertain us, they will give the veterans important information to answer your questions.

sounds cool.....try to get us some pics

Here are photos - I am reassembling the stove, so its not all put back together
(obviously) but you'll get the idea...

The firebox
<removed dead image link>

This is the right side of the base showing the crank handle in position to rotate
the "grinders". There are three covered ports - one for each grinder. When the
handle is removed a metal cover closes off the port so air does not enter.

This is looking down into the firebox - I rotated the middle grinder so you can
see how heavy-duty it is and its triangular shape.

The door - this is the inside part which is covered by an outer cover of the same
brown color as the other external parts.

This is the front panel of the stove - note SUMMIT lettering. This piece is very
heavy duty and is a one piece casting.

This is the top - also very heavy duty and a one piece casting and also very
ornate.

These old circulator stoves are great. I have a smaller one of different make and really like it.

Do all three grates rotate and is the ash pan accessed from a side door? Usually there's two rotating grates and ash door at the front.
Is that a crack (hope not) or a joint that is cemented up?

Yes, three rotating grates. Ash pan is accessed through door on
bottom right - same door that the handle goes thru. There was a
crack in the back of the stove which I welded up and for good
measure cemented over the surface.
What is best for this - nut or stove coal? Anything smaller
just falls thru the grates.

Go with nut, stove can be pretty large. I saved a chunk the last time I bought some, it is the size of a carton of cigarettes!
