Allen's Parlor Furnace 185D

I'm looking for information & possible parts for my Allens Parlor Furnace. This stove was in an abandoned bunk house on our horse farm for the last 60 years or so. The building finally fell down & I drug this thing out. Its mostly complete, althoughnit appears to be missing the ash box, top decorative cover & 1 of the ash grates. I lit a small wood fire in it to burn off some of the rust & free up some stuck parts.

1) How old/rare is it?
2) Are/where parts available?
3) Whats the value?
4) Whats it supposed to burn?
5) Safe to use in my garage?
6) Link to my craigslist ad with pics. http://nashville.craigslist.org/atq/3329727442.html
