As always - if you intend to paint the model, you should paint all of the parts BEFORE assembly. It's much easier that way. I recommend painting the solid "inner" wall pieces in a creamy white - the back wall and forge parts would be made of stone - so grey with black and white dry-brushing. Then dry brush with browns and a little dull green to make it look dirty. All of the other wooden beams should be in a dark brown, possibly very lightly dry brushed with a mid grey. The various tools need to be painted in a variety of colors - I used light brown for then handles and wooden parts and gunmetal for the metal bits. The fireplace and chimney need to be black on the insides - I put splashes of bright red and yellow on the bed of coals at the back of the forge because those would be glowing.
Find the back wall and the seven pieces of the fireplace/chimney:
Flip the back wall part over - so the edged crack lines are underneath and the plain side is uppermost - glue the six side pieces in place (with the etching facing outwards):
Then glue the front piece in place:
Locate the three large timbers that make up the front of the forge and glue those together - set them aside on a FLAT surface while the glue sets:
Locate the side wall parts - glue them together as shown:
Now locate the inner frame parts - note that one A-frame has two pins sticking out at the side - those locate into the side walls
The remaining A-frame is glued behind the front wall and the two diagonal pieces onto the back wall:
...Glue the roof beams into the slots in the A-frames:
The ridge piece (sorry - I didn't grab a photo!) slots into the hole in the chimney and into the two remaining A-frames.
Next - locate the pieces that make up the bed of the fire and glue them together as shown:
Glue that into the underside of the chimney:
Find some of the random twigs and branches and glue those onto the front of the hot coals:
Next assemble the tool rack:
And hang some of the tools from it:
Find the pieces of the anvil (there are two of them):
Glue the sides onto the center piece - then the whole thing onto the plinth:
Lcate the parts for the quenching pit (this would have been a deeper pit with dirty water in it...paint the base accordingly) - glue the sides around the outside of the base:
Locate the parts for the bellows:
Glue those together as shown:
Locate the parts for the buckets (there are several of these) - glue the three layers together:
There are a bunch of sticks and twigs for feeding the fire - or just to scatter around as clutter:
...
Glue the sod roof over the top of the building - then trim off the excess with scissors.
