Cleaning up a Resolute Acclaim 2490

[N_m_1986]

Good morning,
So for my new house I picked up a Craigslist stove,
For about $470 I got the Resolute Acclaim 2490 , MFG date 3007.

For starters is that MFG date 1997, or 2007?

I started taking it apart for cleaning and here are the results from during the cleaning process.

It seems they burned some coal in this stove, which printed on the griddle says is Acceptable! but with coal components?

also, Firebricks were already removed, and I only need one replaced. I can salvage one side brick, and the back wall.

Update: yesterday I re tapped a fireback bolt, frankensteined a firebrick, recemented the other back wall firebricks assembly and resealed the stove back together.
awaiting combustion package, seals, and a handle or two.
good times.
