That one does look as though it needs some mud in the pan. The tuyere sticks up above the floor. I think what I might do though is alter the pan or the tuyere mount so it's flush with the floor or below without needing any fireclay. Clay can be a nuisance in a forge.
That pan kind of looks like it's not original- many of them had cast pans back then, and this one is put together with little angle braces? Not that it matters, but it's a little bit deep for its width. You'll definitely want to cut out a lower section in the lip in the front and back of the pan, to allow longer work to sit right in the fire, even if the floor comes up an inch or two with clay.
Also, although it's not common, some guys even prefer to use anthracite- it just makes a different type of fire than bituminous. More of a heap of coals like a charcoal fire. It'll work if that's all you can find. Deker's right though, bituminous coal is better- though with either type you need to watch out it doesn't have too much sulfur in it. A lot of good coal sellers will know the approximate impurity content and even the "coking button" of their coal.
$250 is probably a decent price, over here it's about the same.
